Syzygies of the transfer ideal of the symmetric group
Harm Derksen, Alexandra Pevzner
We consider the modular action of the symmetric group on when . We show that the image of the transfer map …
Algebraicity of the Brascamp-Lieb constants
Calin Chindris, Harm Derksen
We show that the Brascamp-Lieb (BL) constant BL(-,p) is a semi-algebraic function on the set of feasible data. Consequently, it is algebraic in the sense that it satisfies a polyno…
Tropical Invariants for Permutation Group Actions
Harm Derksen
We consider the action of a permutation group of order on the tropical polynomial semiring in variables. We prove that the sub-semiring of invariant polynomials is fini…
Invariants of finite groups acting on (free) skew fields
Harm Derksen, Jurij Volčič
Let be a finitely generated skew field over a ground field , and let be a finite group of -linear automorphisms of . This paper investigates finite generation of t…
Constructive counterexamples to the additivity of minimum output Rényi entropy of quantum channels for all
Harm Derksen, Benjamin Lovitz
We present explicit quantum channels with strictly sub-additive minimum output Rényi entropy for all , improving upon prior constructions which handled . Our example is p…
Estimating the Euclidean distortion of an orbit space
Ben Blum-Smith, Harm Derksen, Dustin G. Mixon +2
Given a finite-dimensional inner product space and a group of isometries, we consider the problem of embedding the orbit space into a Hilbert space in a way that pres…
