Research description:
As a part of Croatian Science Foundation project 2634 Algebraic and combinatorial methods in vertex algebra theory and Center of Excellence QuantiXLie we study new methods in vertex algebra theory and theory of infinite dimensional Lie algebras. We study certain important classes of vertex algebras like W-algebras and their connection to logarithmic conformal field theory in physics. We use free field realization and screening operators in order to realize vertex algebras and their modules. We construct intertwining operators and calculate fusion rules in categories of modules over certain algebra of Virasoro type (Heisenberg-Virasoro and W(2,2) algebra). Furthermore, we study certain irrational C2-cofinite vertex algebras and their connection to the theory of quantum groups.
Plans for future research:
Continuation of ongoing research and its application to logarithmic conformal field theory. Focus on new results from area of physics and develop appropriate mathematical methods.
