Topological Obstruction in Block-spin Transformations
T. Fujiwara, T. Hayashi, H. Suzuki +1
Block-spin transformations from a fine lattice to a coarse one are shown to give rise to a one-to-one correspondence between the zero-modes of the Ginsparg-Wilson Dirac operators.…

Topological Charge of Lattice Abelian Gauge Theory
T. Fujiwara, H. Suzuki, K. Wu
Configuration space of abelian gauge theory on a periodic lattice becomes topologically disconnected by excising exceptional gauge field configurations. It is possible to define a…
