Mixed Torsion on Right Triangles and the Pólya--Szegő Monotonicity Problem for Regular Polygons

Changfeng Gui, Yeyao Hu, Qinfeng Li +1

Motivated by the polygonal Pólya--Szegő conjecture for torsional rigidity, we study two monotonicity problems for torsional rigidity. The first concerns a mixed torsion problem o…
