Central limit theorem for exponentially quasi-local statistics of spin models on Cayley graphs

open access: yes, 2018
Central limit theorems for linear statistics of lattice random fields (including spin models) are usually proven under suitable mixing conditions or quasi-associativity.

From refined estimates for spherical harmonics to a sharp multiplier theorem on the Grushin sphere [PDF]

open access: yes, 2019
We prove a sharp multiplier theorem of Mihlin-H\"ormander type for the Grushin operator on the unit sphere in $\mathbb{R}^3$, and a corresponding boundedness result for the associated Bochner-Riesz means.

Notes on "quantum gravity" and non-commutative geometry

open access: yes, 2010
I hesitated for a long time before giving shape to these notes, originally intended for preliminary reading by the attendees to the Summer School "New paths towards quantum gravity" (Holbaek Bay, Denmark, May 2008).

Hyperentangled States [PDF]

open access: yes, 1997
We investigate a new class of entangled states, which we call 'hyperentangled',that have EPR correlations identical to those in the vacuum state of a relativistic quantum field.

Ladder operators and endomorphisms in combinatorial Physics [PDF]

open access: yes, 2009
Starting with the Heisenberg-Weyl algebra, fundamental to quantum physics, we first show how the ordering of the non-commuting operators intrinsic to that algebra gives rise to generalizations of the classical Stirling Numbers of Combinatorics. These may

Direct sums and products in topological groups and vector spaces

open access: yes, 2015
We call a subset $A$ of an abelian topological group $G$: (i) $absolutely$ $Cauchy$ $summable$ provided that for every open neighbourhood $U$ of $0$ one can find a finite set $F\subseteq A$ such that the subgroup generated by $A\setminus F$ is contained ...

On the Henstock-Kurzweil Integral for Riesz-space-valued Functions on Time Scales

open access: yes, 2017
We introduce and investigate the Henstock-Kurzweil (HK) integral for Riesz-space-valued functions on time scales. Some basic properties of the HK delta integral for Riesz-space-valued functions are proved.

Topics in chaotic dynamics

open access: yes, 1994
Various kinematical quantities associated with the statistical properties of dynamical systems are examined: statistics of the motion, dynamical bases and Lyapunov exponents.

On the ultraviolet behaviour of quantum fields over noncommutative manifolds

open access: yes, 1998
By exploiting the relation between Fredholm modules and the Segal-Shale-Stinespring version of canonical quantization, and taking as starting point the first-quantized fields described by Connes' axioms for noncommutative spin geometries, a Hamiltonian ...

On the structure of the set of higher order spreading models

open access: yes, 2014
We generalize some results concerning the classical notion of a spreading model for the spreading models of order $\xi$. Among them, we prove that the set $SM_\xi^w(X)$ of the $\xi$-order spreading models of a Banach space $X$ generated by subordinated ...
