Finite Simple Groups as Expanders
Martin Kassabov, Alexander Lubotzky, Nikolay Nikolov
We prove that there exist and such that every non-abelian finite simple group , which is not a Suzuki group, has a set of generators for which the Cayley…
A product decomposition for the classical quasisimple groups
Nikolay Nikolov
We prove that every quasisimple group of classical type is a product of boundedly many conjugates of a quasisimple subgroup of type A_n.
Partial wave expansion and Wightman positivity in conformal field theory
N. M. Nikolov, K. -H. Rehren, I. T. Todorov
A new method for computing exact conformal partial wave expansions is developed and applied to approach the problem of Hilbert space (Wightman) positivity in a non-perturbative fou…
Lectures on Elliptic Functions and Modular Forms in Conformal Field Theory
Nikolay M. Nikolov, Ivan T. Todorov
A concise review of the notions of elliptic functions, modular forms, and theta-functions is provided, devoting most of the paper to applications to Conformal Field Theory (CFT), i…
