Dutch-Belgian discrete math seminar

Special edition DOCTOR at Vrije Universiteit Brussel (VUB), Belgium      

31 May 2024

We are happy to announce DOCTOR (Delightful Occasion for Combinatorial Talks on Outstanding Research), a special edition of the Dutch-Belgian seminar in discrete mathematics at Vrije Universiteit Brussel, on Friday May 31st 2024.

This seminar aims to give young researchers a platform (which was sorely lacking due to COVID) to share their recent results on topics under the umbrella of discrete mathematics. Earlier seminar editions were held at TU/e (3 February 2022, 6 October 2023), VUB (25 May 2022, 31 May 2023, 3 May 2024), UGent (20 January 2023).

The program for this special edition is as follows:

9:45-10:00 OPENING  
10:00-11:00 Leo Storme (UGent) The minimum distance of the code of intersecting lines in PG(3,q) 
11:00-11:15 SHORT BREAK  
11:15-12:15 Simeon Ball (UPC) Practical implementation of geometric quasi-cyclic LDPC codes 
12:15-13:15 LUNCH  
13:15-14:15 Gianira Alfarano (University College Dublin / VUB) Representability of q-matroid products and linear sets 
14:15-14:30 SHORT BREAK  
14:30-15:30 Anurag Bishnoi (TU Delft) Covering grids with multiplicity 
16:30-18:00 PhD defense of Sam Adriaensen (VUB) Stars and Weightlessness in Projective Space  
18:00-... Reception  

The event will take place in building G, sixth floor, room 6.G.52.

Registration is free but mandatory (for logistic reasons, since lunch and coffee will be included) and can be done through the following link: registration form.

The seminar is funded by the Research Foundation Flanders (FWO) and by the Netherlands Organization for Scientific Research (NWO).
