Quadratic quaternion forms, introduced by Seip-Hornix (1965), are special cases of generalized quadratic forms over algebras with involutions. We apply the formalism of
This paper extends the Nilpotent- Jacobian method for sign pattern matrices to complex sign pattern matrices, establishing a means to show that an irreducible complex sign
Consistency for bi(skew)symmetric solutions to systems of generalized Sylvester equations over a finite central algebra.. Linear
Some generalized inverses of partition matrix and quotient identity of generalized Schur complement.. Some resluts on group inverses of block matrices over
Proof : The only problem is to prove formula (4), that is to prove that u is the sum of its Taylor expansion with respect to λ. In the case where A is a complex Banach algebra,
After reminding that global deformations of the Witt, Virasoro, and affine Kac–Moody algebras allow one to retrieve Lie algebras of Krichever–Novikov type, we contract the latter
We describe a num- ber of relationships between the vacuum Verma module of a Virasoro algebra and the Deligne exceptional series of Lie algebras and also some exceptional finite
Lichnerowicz’s algebra of differential geometric operators acting on symmetric tensors can be obtained from generalized geodesic motion of an observer carrying a complex
