On the Höpf Boundary Lemma for quasilinear problems involving singular nonlinearities and applications
Francesco Esposito, Berardino Sciunzi
In this paper we consider positive solutions to quasilinear elliptic problem with singular nonlinearities. We provide a Höpf type boundary lemma via a suitable scaling argument tha…
Affine hyperplane arrangements and Jordan classes
Giovanna Carnovale, Francesco Esposito
We study the geometry of the stratification induced by an affine hyperplane arrangement H on the quotient of a complex affine space by the action of a discrete group preserving H.…
Cell decompositions and algebraicity of cohomology for quiver Grassmannians
Giovanni Cerulli Irelli, Francesco Esposito, Hans Franzen +1
We show that the cohomology ring of a quiver Grassmannian asssociated with a rigid quiver representation has property (S): there is no odd cohomology and the cycle map is an isomor…
Qualitative properties of singular solutions to semilinear elliptic problems
Francesco Esposito, Alberto Farina, Berardino Sciunzi
We consider positive singular solutions to semilinear elliptic problems with possibly singular nonlinearity. We deduce symmetry and monotonicity properties of the solutions via the…
Quotients for sheets of conjugacy classes
Giovanna Carnovale, Francesco Esposito
We provide a description of the orbit space of a sheet S for the conjugation action of a complex simple simply connected algebraic group G. This is obtained by means of a bijection…
Parabolic orbits of -nilpotent elements for classical groups
Magdalena Boos, Giovanni Cerulli Irelli, Francesco Esposito
We consider the conjugation-action of the Borel subgroup of the symplectic or the orthogonal group on the variety of nilpotent complex elements of nilpotency degree in its Lie…
