Gauss sums, superoscillations and the Talbot carpet
F. Colombo, I. Sabadini, D. C. Struppa +1
We consider the evolution, for a time-dependent Schrödinger equation, of the so called Dirac comb. We show how this evolution allows us to recover explicitly (indeed optically) the…
A tropical geometry approach to BIBO stability
Bossoto Bossoto, M Mboup, A Yger
Given a Laurent polynomial F and its amoeba AF. We relate here the question of the BIBO stability of a multi linear time invariant system with a rational transfer function. We form…
Superoscillating sequences and supershifts for families of generalized functions
Fabrizio Colombo, Irene Sabadini, Daniele C. Struppa +1
We construct in this paper a large class of superoscillating sequences, more generally of -supershifts, where is a family of smooth functions (resp. distri…
Nonproper intersection products and generalized cycles
Mats Andersson, Dennis Eriksson, Håkan Samuelsson Kalm +2
In this article we develop intersection theory in terms of the -group of a reduced analytic space. This group was introduced in a previous work as an analogue of the C…
Global representation of Segre numbers by Monge-Ampère products
Mats Andersson, Dennis Eriksson, Håkan Samuelsson Kalm +2
On a reduced analytic space we introduce the concept of a generalized cycle, which extends the notion of a formal sum of analytic subspaces to include also a form part. We then…
About a non-standard interpolation problem
Daniel Alpay, Alain Yger
Using algebraic methods, and motivated by the one variable case, we study a multipoint interpolation problem in the setting of several complex variables. The duality realized by th…
