Algebras and their covariant representations in quantum gravity

Journal of High Energy Physics
We study a physically motivated representation of an algebra of operators in gravitational and non gravitational theories called the covariant representation of an algebra.

On the Meaning of Localization in Non‐Local Quantum Field Theory

Annalen der Physik, Volume 538, Issue 6, June 2026.
In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

Multigraded Hilbert series of noncommutative modules [PDF]

, 2018
In this paper, we propose methods for computing the Hilbert series of multigraded right modules over the free associative algebra. In particular, we compute such series for noncommutative multigraded algebras.

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3018-3037, June 2026.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Categorical Hilbert theory [PDF]

Categorical Hilbert theory is the study of Hilbert spaces and similar kinds of mathematical objects from the perspective of category theory. Similar to the goals of other category-theoretic reformulations of mathematical theories (e.g., abelian ...

Modular flow in JT gravity and entanglement wedge reconstruction

Journal of High Energy Physics
It has been shown in recent works that JT gravity with matter with two boundaries has a type II ∞ algebra on each side. As the bulk spacetime between the two boundaries fluctuates in quantum nature, we can only define the entanglement wedge for each side

Study of Hilbert algebras in point of filters

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
The aim of this work is to introduce some types of filters in Hilbert algebras. Some theorems are stated and proved which determine the relationship between these notions and other filters of Hilbert algebra and by some examples we show that these ...

On generic principal ideals in the exterior algebra

, 2019
We give a lower bound on the Hilbert series of the exterior algebra modulo a principal ideal generated by a generic form of odd degree and disprove a conjecture by Moreno-Socias and Snellman.

A note on homomorphisms of Hilbert algebras

International Journal of Mathematics and Mathematical Sciences, 2002
We give a representation theorem for Hilbert algebras by means of ordered sets and characterize the homomorphisms of Hilbert algebras in terms of applications defined between the sets of all irreducible deductive systems of the associated algebras.
