The Algebra group was visited by Julian Renner for one week in November 2019. Julian is a PhD student at TU Munich and has published several papers with postdoc Sven Puchinger.
During the visit, Johan, Sven, and Julian worked on generic decoding in the sum-rank metric and on low-rank parity-check codes over finite rings. Julian also gave a very nice talk on “Key Compression for Rank-Based Cryptosystems” in the algebra group colloquium.
Update: The visit resulted in two papers accepted at ISIT 2020.
