-Bootstrap
Achilleas Gitsis, Falk Hassler, Luca Scala
Due to the exponential growth in the number of terms, computing -corrections to string theory's low-energy effective actions is a challenging matter. In order to fix all the co…
-Poincaré: bicrossproduct structure, -products and quantum Lie algebra
Luca Scala
We discuss the bicrossproduct structure of the quantum group -Poincaré and of the dual quantum universal enveloping algebra, expanding the construction to general Lie alge…
Generalized Dualities for Heterotic and Type I Strings
Falk Hassler, Yuho Sakatani, Luca Scala
We define generalized dualities for heterotic and type I strings based on consistent truncations to half-maximal gauged supergravities in more than three dimensions. The latter are…
Bicrossproduct vs. twist quantum symmetries in noncommutative geometries: the case of -Minkowski
Giuseppe Fabiano, Giulia Gubitosi, Fedele Lizzi +2
We discuss the quantum Poincaré symmetries of the -Minkowski spacetime, a space characterised by an angular form of noncommutativity. We show that it is possible to give t…
Localization and observers in -Minkowski spacetime
Fedele Lizzi, Luca Scala, Patrizia Vitale
We consider the -Minkowski spacetime, a model with linear noncommutativity involving the time and the azimuthal angle. We study its quantum symmetries, the -Poinc…
Notes on diagonals of the product and symmetric variety of a surface
Luca Scala
Let be a smooth quasi-projective algebraic surface and let the big diagonal in the product variety . We study cohomological properties of the ideal sheaves $\mathcal…
Singularities of the Isospectral Hilbert Scheme
Luca Scala
We study the singularities of the isospectral Hilbert scheme of points over a smooth algebraic surface and we prove that they are canonical if , log-canonical i…
Higher symmetric powers of tautological bundles on Hilbert schemes of points on a surface
Luca Scala
We study general symmetric powers of a tautological bundle on the Hilbert scheme of points over a smooth quasi-projective surface , associa…
Perturbations of the metric in Seiberg-Witten equations
Luca Scala
Let a compact connected orientable 4-manifold. We study the space of -structures of fixed fundamental class, as an infinite dimensional principal bundle on the mani…
Cohomology of the Hilbert scheme of points on a surface with values in representations of tautological bundles
Luca Scala
Let a smooth quasi-projective algebraic surface, a line bundle on . Let the Hilbert scheme of points on and the tautological bundle on $X^{[n…
