On the Star Class Group of a Pullback
Marco Fontana, Mi Hee Park
For the domain arising from the construction , we relate the star class groups of to those of and . More precisely, let be an integral domain, a nonz…
The relativistic shift of narrow spectral features from black-hole accretion discs
T. Pechacek, M. Dovciak, V. Karas +1
Transient spectral features have been discovered in the X-ray spectra of Active Galactic Nuclei, mostly in the 5--7 keV energy range. Several interpretations were proposed for the…
The electron mass from Deformed Special Relativity
Fabio Cardone, Alessio Marrani, Roberto Mignani
Deformed Special Relativity (DSR) is a generalization of Special Relativity based on a deformed Minkowski space, i.e. a four-dimensional space-time with metric coefficients dependi…
Lindstedt series for periodic solutions of beam equations with quadratic and velocity dependent nonlinearities
Vieri Mastropietro, Michela Procesi
We prove the existence of small amplitude periodic solutions, for a large Lebesgue measure set of frequencies, in the nonlinear beam equation with a weak quadratic and velocity dep…
Boosts in an arbitrary direction and maximal causal velocities in a deformed Minkowski space
Fabio Cardone, Alessio Marrani, Roberto Mignani
We discuss boosts in a deformed Minkowski space, i.e. a four-dimensional space-time with metric coefficients depending on non-metric coordinates (in particular on the energy). The…
Singular curves on a K3 surface and linear series on their normalizations
Flaminio Flamini, Andreas Leopold Knutsen, Gianluca Pacienza
In this paper, we study the Brill-Noether theory of the normalizations of singular, irreducible curves on a surface. We introduce a {\em singular} Brill-Noether number $ρ_{sin…
