BV QUANTIZATION OF BRAIDED FIELD THEORIES
In this talk, we will analyze braided noncommutative field theories: spinor and scalar quantum electrodynamics, and phi^3 theory. The classical dynamics of these theories is formulated in the framework of L-infinity algebra, while quantization of these theories is performed using the algebraic BV formalism. We derive algebraic version of correlation functions, Schwinger-Dyson equations and Ward identities based on the homological perturbation lemma.

POINTED HOPF ALGEBRAS OF ODD DIMENSION AND NICHOLS ALGEBRAS OVER SOLVABLE GROUPS
We classify finite-dimensional Nichols algebras of Yetter-Drinfeld modules with indecomposable support over finite solvable groups in characteristic 0, using a variety of methods including reduction to positive characteristic. As a consequence, all Nichols algebras over groups of odd order are of diagonal type, which allows us to describe all pointed Hopf algebras of odd dimension.
This is joint work with I. Heckenberger, L. Vendramin.
Zajednički sastanak sa Odeljenjem za matematiku.
