SoCG Young Researcher’s Forum

Computational Geometry: Young Researchers Forum 2021

Second Call for Submissions

Online, June 7-11, 2021

The 37th Symposium on Computational Geometry (SoCG) will be held virtually June 7-11, 2021 (originally scheduled in Buffalo, USA). It brings together the global community of researchers who work on a large variety of aspects that combine geometry, algorithms and applications. To allow a broad audience to actively participate in the community’s major scientific event, this year SoCG will again be accompanied by a series of satellite events, which together constitute “CG Week 2021”. See for details.

One of these satellite events will be the “Computational Geometry: Young Researchers Forum” (CG:YRF), which is aimed at current and recent students. The active involvement by students and recent graduates in research, discussions, and social events has been longstanding tradition in the CG community. Participation in a top-level event such as SoCG can be educating, motivating, and useful for networking, both with other students and with more senior scientists.

The YRF presents young researchers (defined as not having received a formal doctorate before January 1, 2019) an opportunity to present their work (in progress as well as finished results) to the CG community in a friendly, open setting. Just like in the main event, presentations will be given in the form of talks. A pre-screening (but no formal review process) will ensure appropriate quality control.

Due to COVID-19, it has been decided that the entire CG Week 2021 (including YRF) will be online-only. Specific details about the format will be announced later.

Submission guidelines:


– The idea of the event is for young researchers to present new and ongoing work. Therefore, the work should not have appeared in print in a formally reviewed proceedings volume or journal by the time of submission deadline, and at least one author must be a young researcher.

– Topics must fit into the general context of SoCG, as described in the call for SoCG submissions.

– Submissions must be formatted in accordance with the LIPIcs proceedings guidelines ( and not exceed 80 lines, excluding front matter, references.  To ensure an accurate line counting, authors must use the LaTeX class file socg-lipics-v2019, which is a wrapper around the standard class (available at Authors should refrain from putting excessive amounts of texts in parts in which lines are not counted automatically.

– Submissions can contain an appendix of arbitrary length to provide further details for the screening process, but the main body of the text should be understandable without reading the appendix. Appendices will also not be contained in the booklet (see below).

– The EasyChair submission link is

– Accepted abstracts will be compiled in a booklet of abstracts that will be distributed among the participants; this should not be considered a formal publication. In particular, participants are encouraged to submit (an extended version of) their presented work to a conference with formal proceedings and/or to a journal. Booklets of abstracts from previous years’ YRF are available here:

– The work must be presented at CG:YRF by an author who is a young researcher. Otherwise, it will be removed from the program.

We will employ a two-phase screening process. After the first review phase, there will be a notification of either rejection (if the result is clearly out of scope, or technically incorrect), or conditional acceptance, accompanied with a description of required changes to be made (either with respect to content or format). In the second phase, we will check whether the changes have been implemented satisfactorily. The screening process is intended to ensure the technical quality of the presented work. Submissions that are not well-written risk rejection, irrespective of correctness. Authors are strongly encouraged to have their submissions proofread by their advisor or another experienced scientist.

Important dates (deadlines are 23:59 Anywhere on Earth):


– March 14, 2021: Deadline for submissions

– April 7, 2021: Notification of conditional acceptance

– April 14, 2021: Deadline for revisions

– April 24, 2021: Notification of acceptance

– June 7-11, 2021: CG-Week 2021

NASA Internships in TDA

This summer, NASA Glenn Research Center is hosting several internship opportunities for topology students.  The past several years, we have had interns working on a variety of projects in applied topology.  Past topics have included networking, machine learning, and robotics.

This year, we are hoping to continue several existing research and start some new exciting projects.  We are open to suggestions, and the following list of topics should be considered more for inspiration than as a prescription:

  • Applications of sheaves to communications networks in space
  • Schedule optimization for networks using tropical geometry
    • Develop parallel tools for computing shortest paths (i.e. PyCUDA)
    • Leverage matrices over tropical min-plus semirings
    • Possibly explore the deformation theory of tropical schemes
    • New project for 2021
  • Derive the coordinate-free Vlasov equation using differential forms

Please encourage your students to apply at (Note – the opportunities might not be visible without an account).  Applications are due by March 5, 2021.  If you have any questions, feel free to reach out to me ( or Alan Hylton (

Bedlewo rescheduled: July 2022

There were plans to have an Applied Topology Conference in Bedlewo scheduled for 27 June-3 July 2021. Unfortunately moving forward with the meeting is no longer feasible due to the current  pandemic situation. We are unable to ensure the safety of our participants during the conference time. Moreover, it is very likely that we will have a series of lockdowns in 2021 that may prevent hosting of and participation in the conference impossible without any notice. At the same time we believe that an in person meeting has a key added-value and therefore we are opposed to converting it into a video-conference format.

For these reasons we would like to postpone the conference to 2022, when hopefully we are all able to meet and have a proper scientific event. The new dates for the conference are 3-8 July 2022 for which we pre-booked the same place. In addition to plenary and contributed talks we are planning to have a Young Researcher Forum as well as a poster session. We also plan a sequence of theoretical and software tutorials in Applied Topology on Sunday before the conference (or Saturday just after the main conference).

The accommodation cost in Bedlewo Conference Center is EUR 400 (including accommodation, meals, local transportation, excursion and coffee breaks). A conference fee of  EUR 50 covers the cost of additional social events and the general organization expenses.
We have limited support to partially cover the accommodation fee for participants without sufficient aid from their respective institutions. If you would like to apply for support, please let us know in the “additional information” section of the registration webpage.

The new webpage of the conference is available here:
The pre-registration is open now. Please feel free to register at your earliest convenience, as the number of participants is limited by the capacity of the Bedlewo Conference Center, and we may not be able to accommodate everyone.
If you would like to apply for support or take part in the Young Researcher Forum, please let us know in the “Additional Information” box. Also, please ignore the two tick boxes requesting hotel booking and refunds.

If you have any questions, please do not hesitate to contact me.
We are looking forward to seeing you in Bedlewo in 2022!
