Bounds on the Minimum Eigenvalue Modulus for Hadamard Products of - and -Matrices and Their Inverses
Bharat Pratap Chauhan, Samir Mondal, Sushmitha P
The quantity , the minimum modulus of the eigenvalues of , arises naturally in connection with positive diagonal symmetrizability. For an invertibl…
SNT-Rank: Kronecker Products and Euclidean Distance Matrices
Bharat Pratap Chauhan, Projesh Nath Choudhury
Symmetric nonnegative matrix trifactorizations (SN-Trifactorizations) were introduced by Bukovšek-Šmigoc [Linear Algebra Appl. 2023] as a symmetric analogue of nonnegative matrix f…
On semimonotone matrices of exact order two
Bharat Pratap Chauhan, Dipti Dubey
In this paper, we introduce the notion of (strictly) semimonotone matrices of exact order , where , and explore their properties. We fully characterize the $3 \ti…
On Almost-Type Special Structured Tensor Classes Associated with Semi-Positive Tensors
Bharat Pratap Chauhan, Dipti Dubey
In this paper, we introduce almost (strictly) semi-positive tensors, which extend the concept of almost (strictly) semimonotone matrices. Furthermore, we provide insights into the…
