On the Number of Real Zeros of Random Fewnomials

Peter Bürgisser, Alperen A. Ergür, Josué Tonelli-Cueto

Consider a system $f_{1} (x) = 0, \dots, f_{n} (x) = 0$ of $n$ random real polynomials in $n$ variables, where each $f_{i}$ has a prescribed set of terms described by a set $A\subseteq \mathbb{…
