Topological invariant responsible for the integer QHE and non-commutative geometry
G. Kovyrshin, A. Mekrami, J. Miller +2
We consider a wide class of tight - binding models of solid state physics. These models are, in the most general case, non - homogeneous. The topological invariant ${\cal N}_3…

Structure of renormalization constants for theories with multiple couplings in the MS-like subtraction schemes
Gleb Kovyrshin, Nikolai Meshcheriakov, Victoria Shatalova +1
For theories with multiple couplings we construct simple expressions for the four-dimensional (or, in general, integer-dimensional) renormalization constants assuming that all dive…
