Physics Objects in CMS Run 3
Markus Seidel
In these proceedings we review the physics objects used by the CMS experiment during LHC Run 3 at 13.6 TeV, including charged leptons, photons, jets, and missing transverse momentu…
Approximation sequences on Banach spaces: a rich approach
Helena Mascarenhas, Pedro A. Santos, Markus Seidel
Criteria for the stability of finite sections of a large class of convolution type operators on are obtained. In this class almost all classical symbols are permi…
Computing Spectra -- On the Solvability Complexity Index Hierarchy and Towers of Algorithms
Jonathan Ben-Artzi, Matthew J. Colbrook, Anders C. Hansen +2
This paper establishes some of the fundamental barriers in the theory of computations and finally settles the long-standing computational spectral problem. That is to determine the…
Essential pseudospectra and essential norms of band-dominated operators
Raffael Hagger, Marko Lindner, Markus Seidel
An operator on an -space is called band-dominated if it can be approximated, in the operator norm, by operators with a banded matrix representation. The coset of in th…
On Semi-Fredholm Band-Dominated Operators
Markus Seidel
In this paper we study the semi-Fredholm property of band-dominated operators and prove that it already implies the Fredholmness of in all cases where this is not disqualif…
An Affirmative Answer to a Core Issue on Limit Operators
Marko Lindner, Markus Seidel
An operator on an -space is called band-dominated if it can be approximated, in the operator norm, by operators with a banded matrix representation. It is known that a rich…
