Jordan Decomposition of Non-Hermitian Fermionic Quadratic Forms
Shunta Kitahama, Hironobu Yoshida, Ryo Toyota +1
We give a rigorous proof of Conjecture 3.1 by Prosen [Prosen T 2010 J. Stat. Mech. P07020] on the nilpotent part of the Jordan decomposition of a quadratic fermioni…

Geometric Property (T) and Positive Cones of Real Algebraic Roe Algebras
Ryo Toyota
We give a characterization of geometric property (T) for a coarse disjoint union of finite graphs with bounded degree using the idea of noncommutative real algebraic geometry. In t…

Controlled -theory and -Homology
Ryo Toyota
Motivated by the idea that our access to the spacetime is limited by the resolution of our measuring device, we give a new description of -homology with a finite resolution. G.…
