Stochastically positive structures on Weyl algebras. The case of quasi-free states

, 1997
We consider quasi-free stochastically positive ground and thermal states on Weyl algebras in Euclidean time formulation. In particular, we obtain a new derivation of a general form of thermal quasi-free state and give conditions when such state is ...

An operator expansion for integrable quantum field theories

, 2013
A large class of quantum field theories on 1+1 dimensional Minkowski space, namely, certain integrable models, has recently been constructed rigorously by Lechner.

Knowledge Graph Completion via Complex Tensor Factorization [PDF]

, 2017
In statistical relational learning, knowledge graph completion deals with automatically understanding the structure of large knowledge graphs—labeled directed graphs—and predicting missing relationships—labeled edges.

Operator product expansions as a consequence of phase space properties

, 2005
The paper presents a model-independent, nonperturbative proof of operator product expansions in quantum field theory. As an input, a recently proposed phase space condition is used that allows a precise description of point field structures. Based on the

On Conformal Infinity and Compactifications of the Minkowski Space

, 2010
Using the standard Cayley transform and elementary tools it is reiterated that the conformal compactification of the Minkowski space involves not only the "cone at infinity" but also the 2-sphere that is at the base of this cone.

Martingale inequalities and Operator space structures on $L_p$ [PDF]

, 2013
We describe a new operator space structure on $L_p$ when $p$ is an even integer and compare it with the one introduced in our previous work using complex interpolation.

$C^*$-algebras from planar algebras I: canonical $C^*$-algebras associated to a planar algebra [PDF]

, 2014
From a planar algebra, we give a functorial construction to produce numerous associated $C^*$-algebras. Our main construction is a Hilbert $C^*$-bimodule with a canonical real subspace which produces Pimsner-Toeplitz, Cuntz-Pimsner, and generalized free ...
