Multiparameter twisted Weyl algebras
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012-05-01)
We introduce a new family of twisted generalized Weyl algebras, called multiparameter twisted Weyl algebras, for which we parametrize all simple quotients of a certain kind. Both Jordan's simple localization of the ...
A SURVEY ON FREE OBJECTS IN DIVISION RINGS AND IN DIVISION RINGS WITH AN INVOLUTION
(TAYLOR & FRANCIS INCPHILADELPHIA, 2013-08-02)
Let D be a division ring with center k, and let D-dagger be its multiplicative group. We investigate the existence of free groups in D-dagger, and free algebras and free group algebras in D. We also go through the case ...
The cohomology ring of the 12-dimensional Fomin-Kirillov algebra
(Academic Press Inc Elsevier Science, 2016-03)
The 12-dimensional Fomin-Kirillov algebra FK3 is defined as the quadratic algebra with generators a, b and c which satisfy the relations a2=b2=c2=0 and ab+bc+ca=0=ba+cb+ac. By a result of A. Milinski and H.-J. Schneider, ...
Galois orders in skew monoid rings
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
We introduce a new class of noncommutative rings - Galois orders, realized as certain subrings of invariants in skew semigroup rings, and develop their structure theory. The class of Calms orders generalizes classical ...
