Positivity of Second-Order Nearly Linearly Recurrent Sequences
Amaury Pouly, Mahsa Shirmohammadi, James Worrell
Nearly linear recurrences generalise linear recurrences and can be represented as special cases of both linear time-invariant systems in control theory and linear-constraint loops…

Algebraic Closure of Matrix Sets Recognized by 1-VASS
Rida Ait El Manssour, Mahsa Naraghi, Mahsa Shirmohammadi +1
It is known how to compute the Zariski closure of a finitely generated monoid of matrices and, more generally, of a set of matrices specified by a regular language. This result was…
