MartedÃ¬ 10 giugno, alle ore 10.00, presso l'Aula Benvenuti, la Prof.ssa Cristina Draper Fontanales terrÃ un seminario dal titolo:

"Gradings on Heisenberg type algebras"

Abstract:

Not much is known about gradings on nilpotent or solvable Lie algebras, in spite of the increasing interest in studying sistematically fine gradings on simple Lie algebras, which has culminated with the aparition of the monograph "A. Elduque and M. Kochetov. Gradings on Simple Lie Algebras. Mathematical Surveys and Monographs, Vol 189. Amer. Math. Soc.

2013." (In fact, also simple Lie algebras are much better known than nilpotent ones.)This talk deals with gradings on some families of nilpotent algebras and superalgebras and of solvable algebras. More precisely, we describe group gradings on the Heisenberg algebras $H_n$ (coming from Quantum mechanics), on the Heisenberg superalgebras $H_{n,m}$ and on the twisted Heisenberg algebras $H_n^lambda$ (coming from Differential Geometry).
