Affine isoperimetric inequalities for the first eigenvalue of the -th order Affine -Laplace Operator

Dylan Langharst, Michael Roysdon

Recently, Haddad, Jiménez, and Montenegro introduced the affine -Laplace operator, , and studied associated affine versions of the isoperimetric inequalities for the first…

Functional Liftings of Restricted Geometric Inequalities

Andreas Malliaris, James Melbourne, Cyril Roberto +1

We investigate what we term "generalized sup-convolutions". We show that functional inequalities that enjoy an interpretation as sup-convolution inequalities can be deduced from th…

Affine Isoperimetric Inequalities for Higher-Order Projection and Centroid Bodies

Julián Haddad, Dylan Langharst, Eli Putterman +2

In 1970, Schneider introduced the th order difference body of a convex body, and also established the th-order Rogers-Shephard inequality. In this paper, we extend this idea…

On the th-order Affine Pólya-Szegö Principle

Dylan Langharst, Michael Roysdon, Yiming Zhao

An affine Pólya-Szegö principle for a family of affine energies, with equality condition characterization, is demonstrated. In particular, this recovers, as special cases, the $L…

On the -Order Weighted Projection Body Operator and Related Inequalities

Dylan Langharst, Eli Putterman, Michael Roysdon +1

For a convex body in , the inequalities of Rogers-Shephard and Zhang, written succinctly, are $$\text{vol}_n(DK)\leq \binom{2n}{n} \text{vol}_n(K) \leq \text{vol}_…
