Extremal Polynomial Norms of Graphs
Ãngel Chávez, Sarah Fullerton, Matilda LaFortune +4
Recent work shows that a new family of norms on Hermitian matrices arise by evaluating the even degree complete homogeneous symmetric (CHS) polynomials on the eigenvalues of a Herm…

Stability of Khintchine-type inequalities via log-monotonicity
Ãngel Chávez, Sam Sheng
We investigate Khintchine-type inequalities for the weighted sums of independent copies of a symmetric random variable . We show how log-monotonicity of the seq…

A general framework for inequalities on simple graphs
Ludovick Bouthat, Ãngel Chávez, Sam Sheng
A general framework is developed for deriving sharp inequalities on simple graphs from majorization and Schur-convexity. After establishing majorization relations between the spect…
