Transfer Matrices and Ehrhart Theory for Path and Cyclic Block Polytopes
Xinru Jiang, Shuai Yang, Yueming Zhong
We study block polytopes whose variables are divided into equal-size blocks and whose local inequalities bound the total contribution of adjacent blocks. For blocks arranged along…

Alternating adjacent-sum polytopes: transfer matrices and Ehrhart series
Xinru Jiang, Suzhen Wen, Yueming Zhong
We study a period-two family of adjacent-sum lattice polytopes whose consecutive-coordinate bounds alternate between and . This provides a simple non-uniform deformation o…
