Deformation cone of Tesler polytopes

Yonggyu Lee, Fu Liu

For $a \in R_{\geq 0}^{n}$ , the Tesler polytope $\tes_{n}(\boldsymbol{a})$ is the set of upper triangular matrices with non-negative entries whose hook sum vector is…

Ehrhart positivity of Tesler polytopes and Berline-Vergne's valuation

Yonggyu Lee, Fu Liu

For $\ba \in \R_{\geq 0}^{n}$, the Tesler polytope $\tes_{n}(\ba)$ is the set of upper triangular matrices with non-negative entries whose hook sum vector is $\ba$. Motivated by a…
