The Sigma(1)-invariant For Artin Groups Of Circuit Rank 1

Subspaces with extra invariance nearest to observed data
(Elsevier Inc, 2016-09)
Given an arbitrary finite set of data F = {f1, ..., fm} ⊂ L2(Rd) we prove the existence and show how to construct a “small shift invariant space” that is “closest” to the data F over certain class of closed subspaces of ...
Spectral uniqueness of bi-invariant metrics on symplectic groups
(Birkhauser Boston Inc, 2019-12)
In this short note, we prove that a bi-invariant Riemannian metric on Sp(n) is uniquely determined by the spectrum of its Laplace–Beltrami operator within the class of left-invariant metrics on Sp(n). In other words, on ...

Invariant solutions to the conformal Killing–Yano equation on Lie groups
(2015)
We search for invariant solutions of the conformal Killing–Yano equation on Lie groups equipped with left invariant Riemannian metrics, focusing on 2-forms. We show that when the Lie group is compact equipped with a ...
