Schur-type inequality for solitonic hypersurfaces in $ (k, \mu) $-contact metric manifolds

open access: yesAIMS Mathematics
<p>In this article, we derive a Schur-type Inequality in terms of the gradient $ r $-Almost Newton-Ricci-Yamabe soliton in $ (k, \mu) $-contact metric manifolds. We discuss the triviality for the compact gradient $ r $-Almost Newton-Ricci-Yamabe soliton in $ (k, \mu) $-Contact metric manifolds.

Schur--Horn type inequalities for hyperbolic polynomials

open access: yes
We establish a Schur--Horn type inequality for symmetric hyperbolic polynomials. As an immediate consequence, we resolve a conjecture of Nam Q. Le on Hadamard-type inequalities for hyperbolic polynomials. Our argument is based on the Schur--Horn theorem, the Birkhoff theorem, and Gårding's concavity theorem for hyperbolicity cones.
