Semicircular law with a few independent entries in a random matrix

Debapratim Banerjee, Himasish Talukdar

It is well known in random matrix literature that the limiting spectral distribution of a Wigner matrix is the semi circular law while the limiting spectral distributions of other…

Approximation Theory for Neural Networks: Old and New

Soumendu Sundar Mukherjee, Himasish Talukdar

Universal approximation theorems provide a mathematical explanation for the expressive power of neural networks. They assert that, under mild conditions on the activation function,…

Elephant random walk on the infinite dihedral group

Soumendu Sundar Mukherjee, Himasish Talukdar

Elephant random walks were studied recently in \cite{mukherjee2025elephant} on the groups whose Cayley graphs are infinite -regular tre…

Spectra of contractions of the Gaussian Orthogonal Tensor Ensemble

Soumendu Sundar Mukherjee, Himasish Talukdar

In this article, we study the spectra of matrix-valued contractions of the Gaussian Orthogonal Tensor Ensemble (GOTE). Let denote a random tensor of order and dim…

Spectra of adjacency and Laplacian matrices of Erdős-Rényi hypergraphs

Soumendu Sundar Mukherjee, Dipranjan Pal, Himasish Talukdar

We study adjacency and Laplacian matrices of Erdős-Rényi -uniform hypergraphs on vertices with hyperedge inclusion probability , in the setting where can vary with $n…

Bulk Spectra of Truncated Sample Covariance Matrices

Subhroshekhar Ghosh, Soumendu Sundar Mukherjee, Himasish Talukdar

Determinantal Point Processes (DPPs), which originate from quantum and statistical physics, are known for modelling diversity. Recent research [Ghosh and Rigollet (2020)] has demon…
