Gradings on walled Brauer algebras and Khovanov's arc algebra

Abstract: We introduce some graded versions of the walled Brauer algebra, working over a field of characteristic zero. This allows us to prove that the walled Brauer algebra is Morita equivalent to an...

All gradings by abelian groups are classified on the following al-gebras over an algebraically closed field F: the simple Lie algebra of type G2 (char F 6= 2, 3), the exceptional simple Jordan algebra...
