-deformed harmonic oscillators
F. Bagarello, F. Gargano, D. Volpe
We analyze systematically several deformations arising from two-dimensional harmonic oscillators which can be described in terms of -pseudo bosons. They all give rise to e…
A Phenomenological Operator Description of Dynamics of Crowds: Escape Strategies
Fabio Bagarello, Francesco Gargano, Francesco Oliveri
We adopt an operatorial method, based on creation, annihilation and number operators, to describe one or two populations mutually interacting and moving in a two--dimensional regio…
Viscous-Inviscid Interactions in a Boundary-Layer Flow Induced by a Vortex Array
Francesco Gargano, Marco Sammartino, Vincenzo Sciacca +1
In this paper we investigate the asymptotic validity of boundary layer theory. For a flow induced by a periodic row of point-vortices, we compare Prandtl's solution to Navier-Stoke…
Model pseudofermionic systems: connections with exceptional points
F. Bagarello, F. Gargano
We discuss the role of pseudo-fermions in the analysis of some two-dimensional models, recently introduced in connection with non self-adjoint hamiltonians. Among other aspects, we…
A spectral approach to a constrained optimization problem for the Helmholtz equation in unbounded domains
Giulio Ciraolo, Francesco Gargano, Vincenzo Sciacca
We study some convergence issues for a recent approach to the problem of transparent boundary conditions for the Helmholtz equation in unbounded domains. The approach is based on t…
