Computing the Skyscraper Invariant
Marc Fersztand, Jan Jendrysiak
We develop the first algorithms for computing the Skyscraper Invariant [FJNT24]. This is a filtration of the classical rank invariant for multiparameter persistence modules defined…
Harder-Narasimhan filtrations of persistence modules: metric stability
Marc Fersztand
The Harder-Narasimhan types are a family of discrete isomorphism invariants for representations of finite quivers. Previously (arXiv:2303.16075), we evaluated their discriminating…
Harder-Narasimhan Filtrations of Persistence Modules
Marc Fersztand, Emile Jacquard, Vidit Nanda +1
The Harder-Narasimhan type of a quiver representation is a discrete invariant parameterised by a real-valued function (called a central charge) defined on the vertices of the quive…
Harder-Narasimhan Filtrations and Zigzag Persistence
Marc Fersztand, Vidit Nanda, Ulrike Tillmann
We introduce a sheaf-theoretic stability condition for finite acyclic quivers. Our main result establishes that for representations of affine type quivers,…
On algebraic integers all conjugates of which belong to a given compact subset of the complex plane
Marc Fersztand, Benjamin Gourevitch, Arnaud Rippol +3
The study of Frobenius endomorphism provides numerous information about its corresponding Abelian variety. To understand the action of the Frobenius endomorphism, one may be intere…
