摘要:
We continue the classification, begun in [11], [14] and [12], of quadratic Artin-Schelter regular algebras of global dimension 4 which map onto a twisted homogeneous coordinate ring of a quadric hypersurfcice in P3. In this paper, we consider those cases where the quadric has rank 3. We also give sufficient conditions for the point scheme of any quadratic regular algebra of global dimension 4 to be the graph of an automorphism.

摘要:
We compute the fibers of the canonical map from Weyl group elements to orbital varieties for a Lie algebra of typeB,C, orD. We also compute one irreducible component of the associated variety of any simple highest weight module in any classical type, thereby sharpening a result of Joseph and partially proving a conjecture of Tanisaki.

摘要:
Associated to any eight-dimensional non-unital composition algebra with associative norm, there are outer automorphisms of order 3 of the corresponding spin group, such tiat the fixed subgroup is the automorphism group of the composition algebra. Over fields of characteristic ≠ 3 these are simple algebraic groups of typesG2orA2, related respectively to the para-octonion and the Okubo algebras

摘要:
A proper regular action of the additive group of complex numbers on complex affine space is known to be locally trivial if the coordinate ring of affine space is a flat extension of the ring ofGainvariants. Conditions under which a separated action is locally trivial are examined (Section 2) and an algorithm to determine the local triviality of any given action is presented (Section 3).
