The amenability constant of the Fourier algebra

Volker Runde

For a locally compact group , let denote its Fourier algebra and its dual object, i.e. the collection of equivalence classes of unitary represenations of . W…

Indispensable Role of Quantum Theory in the Brain Dynamics

Yukinari Kurita

Recently, Tegmark pointed out that the superposition of ion states involved in the superposition of firing and resting states of a neuron quickly decohere. It undoubtedly indicates…

On the hardness of distinguishing mixed-state quantum computations

Bill Rosgen, John Watrous

This paper considers the following problem. Two mixed-state quantum circuits Q and R are given, and the goal is to determine which of two possibilities holds: (i) Q and R act nearl…

On convexified packing and entropy duality

S. Artstein, V. Milman, S. J. Szarek +1

A 1972 duality conjecture due to Pietsch asserts that the entropy numbers of a compact operator acting between two Banach spaces and those of its adjoint are (in an appropriate sen…

Learning for Adaptive Real-time Search

Vadim Bulitko

Real-time heuristic search is a popular model of acting and learning in intelligent autonomous agents. Learning real-time search agents improve their performance over time by acqui…

Automorphisms and twisted loop algebras of finite dimensional simple Lie superalgebras

Dimitar Grantcharov, Arturo Pianzola

We describe the structure of the algebraic group of automorphisms of all simple finite dimensional Lie superalgebras. Using this and étale cohomology considerations, we list all di…
