Generalization of lattice Dirac operator index
Shoto Aoki, Hajime Fujita, Hidenori Fukaya +4
We provide a comprehensive lattice formulation of various types of the Dirac operator indices, employing -theory to classify the Wilson Dirac operator via its spectral flow. In…

Weighted sums of rooted spanning forests on cycles with pendant edges
Hajime Fujita, Kimiko Hasegawa, Yukie Inaba +1
We derive two formulas for the weighted sums of rooted spanning forests of particular sequence of graphs by using the matrix tree theorem. We consider cycle graphs with edges so ca…

The generalized Pythagorean theorem on the compactifications of certain dually flat spaces via toric geometry
Hajime Fujita
In this paper we study dually flat spaces arising from Delzant polytopes equipped with a symplectic potential together with their corresponding toric Kähler manifolds as their tori…
