Nikhil Bansal: On a generalization of iterated and randomized rounding
The lecture was held within the framework of the follow-up workshop to the Hausdorff Trimester Program: Combinatorial Optimization. We describe a new rounding procedure that optimally combines the benefits of both iterated rounding and randomized rounding. A nice feature of this procedure

Monique Laurent: Combinatorial and algorithmic properties of Robinsonian matrices
Abstract: Robinsonian matrices are structured matrices that have been introduced in the 1950's by the archeologist W.S. Robinson for chronological dating of Egyptian graves. A symmetric matrix is said to be Robinsonian if its rows and columns can be simultaneously reordered in such a way t

Bento Natura: On circuit imbalance measures and their role in circuit augmentation algorithms
The efficiency of many algorithms for linear programs and integer programs crucially depends on condition numbers of the constraint matrix. We motivate new combinatorial condition numbers that bound the ratio of non-zero entries of support-minimal vectors in the kernel of the constraint ma

Peter Varju: Additive combinatorics methods in fractal geometry - lecture 2
In the last few years ideas from additive combinatorics were applied to problems in fractal geometry and led to progress on some classical problems, particularly on the smoothness of Bernoulli convolutions and other self-similar measures. We will introduce some of these tools from additive

Urs Lang (2/3/23): Combinatorial dimension and higher-rank hyperbolicity
Dress characterized metric spaces of combinatorial dimension at most n in terms of a 2(n+1)-point inequality. We investigate a relaxed version of this inequality, which in the case n = 1 reduces to Gromov's quadruple definition of δ-hyperbolicity and which we experimentally call (n,δ)-hype
