A differential algebra and the homotopy type of the complement of a toric arrangement
Corrado De Concini, Giovanni Gaiffi
We show that the rational homotopy type of the complement of a toric arrangement is completely determined by two sets of combinatorial data. This is obtained by introducing a diffe…
Cohomology rings of compactifications of toric arrangements
Corrado De Concini, Giovanni Gaiffi
Some projective wonderful models for the complement of a toric arrangement in a n-dimensional algebraic torus T were constructed in [3]. In this paper we describe their integer coh…
On some modules of covariants for a reflection group
Corrado De Concini, Paolo Papi
Let be a simple Lie algebra with Cartan subalgebra and Weyl group . We build up a graded map $(\mathcal H\otimes \bigwedge\mathfrak h\otimes \mathfra…
On special covariants in the exterior algebra of a simple Lie algebra
Corrado De Concini, Pierluigi Möseneder Frajria, Paolo Papi +1
We study the subspace of the exterior algebra of a simple complex Lie algebra linearly spanned by the copies of the little adjoint representation or, in the case of the Lie algebra…
A generalized Steinberg section and branching rules for quantum groups at roots of 1
Corrado De Concini, Andrea Maffei
In this paper we construct a generalization of the classical Steinberg section for the quotient map of a semisimple group with respect to the conjugation action. We then give vario…
The infinitesimal index
Corrado de Concini, Claudio Procesi, Michele Vergne
In this note, we study an invariant associated to the zeros of the moment map generated by an action form, the infinitesimal index. This construction will be used to study the comp…
