Quantum -deformations of D=4 relativistic supersymmetries
Jerzy Lukierski
We describe the quantum -deformation of super-Poincaré algebra, with fundamental mass-like deformation parameter . We shall describe the result in graded bicrossproduct basis…
Twistorial versus space--time formulations: unification of various string models
Sergey Fedoruk, Jerzy Lukierski
We introduce the D=4 twistorial tensionfull bosonic string by considering the canonical twistorial 2--form in two--twistor space. We demonstrate its equivalence to two bosonic stri…
Jordanian Twist Quantization of D=4 Lorentz and Poincare Algebras and D=3 Contraction Limit
A. Borowiec, J. Lukierski, V. N. Tolstoy
We describe in detail two-parameter nonstandard quantum deformation of D=4 Lorentz algebra , linked with Jordanian deformation of .…
Quantum Deformations of Einstein's Relativistic Symmetries
Jerzy Lukierski
We shall outline two ways of introducing the modification of Einstein's relativistic symmetries of special relativity theory - the Poincaré symmetries. The most complete way of int…
Galilean Exotic Planar Supersymmetries and Nonrelativistic Supersymmetric Wave Equations
J. Lukierski, I. Prochnicka, P. C. Stichel +1
We describe the general class of -extended Galilean supersymmetries obtained, respectively, from the -extended D=3 Poincaré superalgebras with maximal sets of centr…
