Generalized minimum distance functions and algebraic invariants of Geramita ideals

Susan M. Cooper, Alexandra Seceleanu, Stefan O. Tohaneanu +2

Motivated by notions from coding theory, we study the generalized minimum distance (GMD) function $δ_{I} (d, r)$ of a graded ideal $I$ in a polynomial ring over an arbitrary field usin…

On ideals generated by fold products of linear forms

Stefan Tohaneanu

Let $K$ be a field of characteristic 0. Given $n$ linear forms in $R = K [x_{1}, \dots, x_{k}]$ , with no two proportional, in one of our main results we show that the ideal…

Equivalent matrices up to permutations

Stefan O. Tohaneanu, Jesus Vargas

Given two $k \times n$ matrices $A$ and $B$ , we describe a couple of methods to solve the matrix equation $X A = B Y$ , where $X$ is an invertible $k \times k$ matrix, and $Y$ is an $n\ti…
