On Twist Quantizations of D=4 Lorentz and Poincare Algebras
A. Borowiec, J. Lukierski, V. N. Tolstoy
We use the decomposition of o(3,1)=sl(2;C)_1\oplus sl(2;C)_2 in order to describe nonstandard quantum deformation of o(3,1) linked with Jordanian deformation of sl(2;C}. Using twis…

Three-Dimensional Chern-Simons and BF Theories
A. Borowiec, M. Francaviglia
Our aim in this note is to clarify a relationship between covariant Chern-Simons 3-dimensional theory and Schwartz type topological field theory known also as BF theory.
