Evenly positive definite function of Hilbert space and some algebraic relationship

open access: yesМатематичні Студії, 2021
A generalization of P. A. Minlos, V. V. Sazonov’s theorem is proved in the case of bounded evenly positive definite function given in a Hilbert space.

Exploring Free Matrix CFT Holographies at One-Loop

open access: yesUniverse, 2017
We extend our recent study on the duality between stringy higher spin theories and free conformal field theories (CFTs) in the S U ( N ) adjoint representation to other matrix models, namely the free S O ( N ) and S p ( N ...

On the N↔−N self-duality of su(N) theories

open access: yesNuclear Physics B
We generalize N↔−N duality of dimension formulae of SU(N) representations on a (class of the) representations with N-dependent Young diagrams, including adjoint representation.

Scientific Theories as Intervening Representations

open access: yesTheoria, 2010
In this paper we use some ideas of Hertz and Duhem to propose a new concept of representation that overcomes the dichotomy between representation and intervention.

Continuous energy adjoint transport for photons in PHITS

open access: yesEPJ Web of Conferences, 2017
Adjoint Monte Carlo can be an effcient algorithm for solving photon transport problems where the size of the tally is relatively small compared to the source. Such problems are typical in environmental radioactivity calculations, where natural or fallout

Gauging 1-form center symmetries in simple SU(N) gauge theories

open access: yesJournal of High Energy Physics, 2020
Consequences of gauging exact ℤ k C $$ {\mathbb{Z}}_k^C $$ center symmetries in several simple SU(N) gauge theories, where k is a divisor of N, are investigated.

CAD Integrated Multipoint Adjoint-Based Optimization of a Turbocharger Radial Turbine

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2017
The adjoint method is considered as the most efficient approach to compute gradients with respect to an arbitrary number of design parameters. However, one major challenge of adjoint-based shape optimization methods is the integration into a computer ...

Partition function of free conformal fields in 3-plet representation

open access: yesJournal of High Energy Physics, 2017
Simplest examples of AdS/CFT duality correspond to free CFTs in d dimensions with fields in vector or adjoint representation of an internal symmetry group dual in the large N limit to a theory of massless or massless plus massive higher spins in AdS d+1.

Development of a variational flux inversion system (INVICAT v1.0) using the TOMCAT chemical transport model [PDF]

open access: yesGeoscientific Model Development, 2014
We present a new variational inverse transport model, named INVICAT (v1.0), which is based on the global chemical transport model TOMCAT, and a new corresponding adjoint transport model, ATOMCAT.
