Thom series in negative relative codimension
László M. Fehér, Ákos K. Matszangosz
We develop a theory of Thom series for contact function singularities. Quadratic stabilization of a contact singularity gives contact singularities $σ_q^{i}η\…
Triplets of Mutually Unbiased Bases
Máte Matolcsi, Ákos K. Matszangosz, Dániel Varga +1
We initiate a systematic study of triplets of mutually unbiased bases (MUBs). We show that in each MUB-triplet is characterized by a object that…
Obstructions for Morin and fold maps: Stiefel-Whitney classes and Euler characteristics of singularity loci
László M. Fehér, Ákos K. Matszangosz
For a singularity type , let the -avoiding number of an -dimensional manifold be the lowest for which there is a map without type singul…
A characterization of complex Hadamard matrices appearing in families of MUB triplets
Ákos K. Matszangosz, Ferenc Szöllősi
It is shown that a normalized complex Hadamard matrix of order having three distinct columns, each containing at least one entry necessarily belongs to the transposed Four…
The mod 2 cohomology rings of oriented Grassmannians via Koszul complexes
Ákos K. Matszangosz, Matthias Wendt
We study the structure of mod 2 cohomology rings of oriented Grassmannians of oriented -planes in . Our main focus is on the struc…
Similarity and Matching of Neural Network Representations
Adrián Csiszárik, Péter Kőrösi-Szabó, Ákos K. Matszangosz +2
We employ a toolset -- dubbed Dr. Frankenstein -- to analyse the similarity of representations in deep neural networks. With this toolset, we aim to match the activations on given…
On the cohomology rings of real flag manifolds: Schubert cycles
Ákos K. Matszangosz
We give an algorithm to compute the integer cohomology groups of any real partial flag manifold, by computing the incidence coefficients of the Schubert cells. For even flag manifo…
Real solutions of a problem in enumerative geometry
László M. Fehér, Ákos K. Matszangosz
We study a 2-parameter family of enumerative problems over the reals. Over the complex field, these problems can be solved by Schubert calculus. In the real case the number of solu…
