Module theory over the exterior algebra with applications to combinatorics
Acknowledgements My deepest thanks go to Tim Römer for his guidance into mathematics and mathematical life since many years now, his support and encouragement during all that time. I wish to thank Winfried Bruns for his interest and many warm and refreshing conversations. I thank Christof and Jochen for always listening to my more or more often less exigent problems. I would also like to thank ...
متن کاملAdjunctions between Hom and Tensor as endofunctors of (bi-) module category of comodule algebras over a quasi-Hopf algebra.
For a Hopf algebra H over a commutative ring k and a left H-module V, the tensor endofunctors V k - and - kV are left adjoint to some kinds of Hom-endofunctors of _HM. The units and counits of these adjunctions are formally trivial as in the classical case.The category of (bi-) modules over a quasi-Hopf algebra is monoidal and some generalized versions of Hom-tensor relations have been st...
متن کاملFlips and the Hilbert Scheme over an Exterior Algebra
We study the tangent space at a monomial point M in the Hilbert scheme that parameterizes all ideals with the same Hilbert function as M over an exterior algebra.
متن کاملThe exterior algebra and ‘ Spin ’ of an orthogonal g - module Dmitri
The symmetric algebra of a (finite-dimensional) g-module V is the algebra of polynomial functions on the dual space V . Therefore one can study the algebra of symmetric invariants using geometry of G-orbits in V ∗ . In case of the exterior algebra, ∧•V, lack of such geometric picture results by now in absence of general structure theorems for the algebra of skew-invariants (∧•V)g . One may find...
متن کاملAn extensible module algebra for Maude
The fact that rewriting logic and Maude are reeective, so that rewriting logic speciications can be manipulated as terms at the metalevel, opens up the possibility of deening an algebra of module composition and transformation operations within the logic. This makes such a module algebra easily modiiable and extensible, enables the implementation of language extensions within Maude, and allows ...
