Moving-Average Iteration of Linear Maps
Jeremias Epperlein, Fabian Wirth
We consider moving-average iteration for fixed complex matrices and place the theory in the general context of Krasnoselskii and Mann iteration. Necessary and sufficient spectral c…
Lower Bounds for the Shadiness Constant of Finite-Dimensional Normed Spaces
Jeremias Epperlein
By the Hahn-Banach theorem, every normed space admits rank-one projections with operator norm one. However, this is not true for higher rank projections. Bosznay and Garay showed t…
Auerbach bases, projection constants, and the joint spectral radius of principal submatrices
Jeremias Epperlein, Fabian Wirth
It is shown that compact sets of complex matrices can always be brought, via similarity transformation, into a form where all matrix entries are bounded in absolute value by the jo…
Hyperspatiality for isomorphisms of stabilized automorphism groups of shifts of finite type
Jeremias Epperlein, Scott Schmieding
Given a homeomorphism of a compact metric space , the stabilized automorphism group of the system is the group of self-home…
The joint spectral radius is pointwise Hölder continuous
Jeremias Epperlein, Fabian Wirth
We show that the joint spectral radius is pointwise Hölder continuous. In addition, the joint spectral radius is locally Hölder continuous for -inflations. In the two-…
Eventual Conjugacy of Free Inert -SFTs
Jeremias Epperlein
The action of a finite group on a subshift of finite type is called free, if every point has trivial stabilizer, and it is called inert, if the induced action on the dimens…
