Finite entanglement entropy and spectral dimension in quantum gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
What are the conditions on a field theoretic model leading to a finite entanglement entropy density? We prove two very general results: (1) Ultraviolet finiteness of a theory does not guarantee finiteness of the entropy density; (2) If the spectral ...

A Four-Dimensional Theory for Quantum Gravity with Conformal and Nonconformal Explicit Solutions [PDF]

open access: yes, 1994
The most general version of a renormalizable $d=4$ theory corresponding to a dimensionless higher-derivative scalar field model in curved spacetime is explored.

Ontology and semantics: An anti-realistic reading of the Tractatus [PDF]

open access: yesBelgrade Philosophical Annual, 2017
According to the received view, the Tractatus would present a realistic conception of the meaning of a declarative sentence: that meaning would be explained in terms of evidence-transcending, not epistemically-constrained, truth-conditions. In this paper,

Finiteness in derived categories of local rings [PDF]

open access: yes, 2005
New homotopy invariant finiteness conditions on modules over commutative rings are introduced, and their properties are studied systematically. A number of finiteness results for classical homological invariants like flat dimension, injective dimension ...

A finiteness condition on the coefficients of the probabilistic zeta function [PDF]

open access: yesInternational Journal of Group Theory, 2013
We discuss whether finiteness properties of a profinite group $G$ can be deduced from the coefficients of the probabilisticzeta function $P_G(s)$. In particular we prove that if $P_G(s)$ is rational and all but finitely many non abelian composition ...

Noetherian and Artinian ordered groupoids—semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Chain conditions, finiteness conditions, growth conditions, and other forms of finiteness, Noetherian rings and Artinian rings have been systematically studied for commutative rings and algebras since 1959.

Fractal Dimension for the Nonautonomous Stochastic Fifth-Order Swift–Hohenberg Equation

open access: yesComplexity, 2020
Some dynamics behaviors for the nonautonomous stochastic fifth-order Swift–Hohenberg equation with additive white noise are considered. The existence of pullback random attractors for the nonautonomous stochastic fifth-order Swift–Hohenberg equation with

Locally Finite Groups Saturated with Direct Product of Two Finite Dihedral Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
In the study of infinite groups, as a rule, some finiteness conditions are imposed. For example, the group is required to be periodic, Shunkov group, Frobenius group, locally finite group.

On the discrete spectrum of Robin Laplacians in conical domains [PDF]

open access: yes, 2015
We discuss several geometric conditions guaranteeing the finiteness or the infiniteness of the discrete spectrum for Robin Laplacians on conical domains.Comment: 12 ...
