Call for Proposals: Trimester Programs

A proposal for a Trimester Program should be written in such a way that the members of the Scientific Advisory Board get a clear picture of the state of the art and the aims of the program. The Institute is open for all areas of mathematics, mathematical economics, and mathematical physics. Given the different cultures of these areas the Institute gives a lot of freedom how to compose a program. However, the organization of a summer respectively winter school for students during the Trimester Program is obligatory. There will be three programs in the period between September 2022 and August 2023: the fall program from September to December, the winter program from January to April, and the summer program from May to August.

The following scheme has turned out to be successful. We have office space for about 30 people. The idea is to fill these places with about 10 senior scientists, 10 postdocs, and 10 PhD students. It is very important for the success of a program to make sure that at any time there are enough senior scientists participating in the program. Thus a proposal should contain names of senior scientists who come for longer periods (at least one month). Applicants should contact such people and ask them whether they would come for a longer period if the program is approved. It would be good to attach mails from these colleagues where they give a positive answer. In addition, the contact data of all organizers including the current academic status and the affiliation should be listed. After the program is approved we ask the applicants to update the information about participating senior scientists. The Institute will then send out invitations to them. We will write the names of these people on the poster announcing the program. On the same poster we ask postdocs and PhD students for applications.

HIM encourages proposals which have the potential to establish new collaboration across different research communities, either within mathematics or between mathematics and its applications. Organizing teams which make the case that recent scientific developments demonstrate such potential may apply for a "Dual Trimester Program".

The deadline for next submitting a proposal will the end of September 2020. The decision of the Scientific Advisory Board will be made at the end of January 2021. The Scientific Advisory Board decides about three programs taking place in the period between September 2022 and August 2023. One of these three programs will be a Junior Trimester Program. For a Junior Trimester Program proposals are not expected. The Scientific Advisory Board determines a theme for such a program. Positions are then announced on the poster.

The Institute wishes to increase the number of female participants. In view of this policy, proposals with at least one female organizer are strongly encouraged.

Proposals can be sent in at any time until September. They should be sent (preferably by e-mail) to:

Prof. Dr. Christoph Thiele 
Director of HIM 
Poppelsdorfer Allee 45
53115 Bonn, Germany



Could you specify the requirements for the proposals?

There are no formal requirements. But we recommend a proposal to contain the following key items:

  • title page with title, organizers with affiliations, and proposed slots (first and second choice)
  • brief description of the overall aims of the trimester program
  • core topics of the Trimester Program, important developments and goals
  • planned activities (workshops, roughly one per month, one obligatory Summer or Winter School) and a list of possible additional organizers beyond TP organizers for these activities
  • a list of and commitments by possible long-term participants (with a stay of at least 15 consecutive days) and short-term guests
  • bibliography

How high is the budget for a trimester program? 

The overall budget for the Trimester Program is 330.000 €, 90.000 € of which is in particular reserved for junior researchers. There is an additional budget of up to 25.000 € for the organization of a School. All payments to participants and all costs for additional activities such as workshops must come from the budget. HIM usually pays a monthly fellowship to long-term guests, from which they pay all expenses, i.e. travel, housing, meals, and so on. As a basic principle, HIM does not pay travel subsidies to senior scientists. For short-term guests we arrange and cover the costs for single accommodation in addition to disbursing a small per diem in cash. In general, HIM does not reimburse travel costs of workshop participants (not even for PhD students or postdocs).

What do the organizers have to do after the program is accepted and before the program starts?

  • Invitation to experts
    The organizers should contact experts in due time, clarify with them on the possible dates of their visits and whether they are willing to be mentioned on the poster. The official invitations will be sent out by the Director of HIM as soon as the organizers have provided a list of experts including all email addresses and these people have registered to the program.
  • Poster
    In consultation with the organizers, HIM designs a poster which should be sent out approximately one year before the program starts. The organizers have to propose a text and provide an image for the poster. Some experts who have already confirmed their participation should be mentioned on the poster. The titles/topics and approximate dates of the planned workshops should be mentioned on the poster, so that prospective participants can time their dates of stay accordingly. HIM has an international distribution list containing approx. 800 institutions. The costs for the production and distribution of the poster will be paid by HIM separately and not deducted from the total Trimester Program budget.  
  • Organization of a School
    The organization of a School is obligatory. The organizers should contact possible lecturers in due time and determine a week of this event. The organizers should nominate up to 4 key speakers, which have to be present for a minimum of 3 days and hold a minimum of 3 talks. Other (non-key) speakers can be invited as the organizers deem relevant. In consultation with the organizers, HIM will design a poster for the School.
  • Invitation to participants
    HIM puts an online application form on the website of the Trimester Program. After the deadline for applications has expired, the organizers can examine the applications (including letters of intent, CVs, lists of publications, and recommendation letters) online. The organizers will design a list of guests who obtain an invitation. Of course it is possible to send out additional invitations during the program.
  • Organization of workshops
    If the organizers have already decided to organize a workshop, the organizers and the HIM Director agree on a list of participants and HIM administration sends out invitations several months before the event starts. Small activities can be initiated spontaneously during the Trimester Program, but longer term planning is appreciated and encouraged. 

What if long-term participants or organizers need to leave Bonn on business (conference, collaboration)?
Absences are possible, though not encouraged. It is important that the number of days of absence is in reasonable relation to the entire stay at HIM, and that the trip is for business. The rule is that the Director has to be informed in advance if a long-term guest intends to leave Bonn for two or more working days within a week. Absences of short-term guests (stays < 1 month) are not encouraged.

How much office space is available?
There are 30 work desks at the Institute. There are about 15 more work desks in Poppelsdorfer Allee 82 available for HIM. In this building, also the HIM administration is located. Participants of workshops do not get offices.

Where do the lectures and talks take place?
The HIM Lecture Hall accommodates up to 60 persons. Standard equipment includes chairs (w/o desks or tables), overhead projector, beamer with screen and connected PC (presentations on a USB stick), 2-part chalk board (vertical extension), and air conditioning. Video recording is possible and a sound system can be installed on demand.  A video streaming from the main Lecture Hall at HIM to a second lecture room is permanently installed. In the second lecture room, another 20 persons can follow the talks.

How can organizers and participants find information or contact persons for questions about housing, family support, computer support, visa problems, health insurance, travel to Bonn, entertainment and culture in Bonn, language courses and so on?
