Algebraic connectivity of layered path graphs under node deletion
Ryusei Yoshise, Kaoru Yamamoto
This paper studies the relation between node deletion and algebraic connectivity for graphs with a hierarchical structure represented by layers. To capture this structure, the conc…

Jacobi identity in polyhedral products
Daisuke Kishimoto, Takahiro Matsushita, Ryusei Yoshise
We show that a relation among minimal non-faces of a fillable complex yields an identity of iterated (higher) Whitehead products in a polyhedral product over . In particular…
