Quantization of pseudo-differential operators on the torus [PDF]
, 2008 Pseudo-differential and Fourier series operators on the n-torus are analyzed by using global representations by Fourier series instead of local representations in coordinate charts.

Aperiodic order and spherical diffraction, II: Translation bounded measures on homogeneous spaces [PDF]
, 2020 We study the auto-correlation measures of invariant random point processes in the hyperbolic plane which arise from various classes of aperiodic Delone sets. More generally, we study auto-correlation measures for large classes of Delone sets in (and even

On the Duality of Discrete and Periodic Functions
Mathematics, 2015 Although versions of Poisson’s Summation Formula (PSF) have already been studied extensively, there seems to be no theorem that relates discretization to periodization and periodization to discretization in a simple manner.

Approximation of the effective conductivity of ergodic media by periodization [PDF]
, 2003 This paper is concerned with the approximation of the effective conductivity $\sigma(A,\mu)$ associated to an elliptic operator $\nabla_x A(x,\eta) \nabla_x$ where for $x\in \R^d$, $d\geq 1$, $A(x,\eta)$ is a bounded elliptic random symmetric $d\times d$

Periodization of literary history (background, philosophical origins and functions) [PDF]
تاریخ ادبیات, 2013 Historical studies, among the ways of classifying historical information, are most inclined to periodization. Periodization divides historical information in the time axis.

Application of Boyd’s periodization and relaxation method in a spectral atmospheric limited-area model, part II : accuracy analysis and detailed study of the operational impact [PDF]
, 2012 Spectral limited-area models face a particular challenge at their lateral boundaries: the fields need to be made periodic. Boyd proposed a windowing-based method to improve the periodization and relaxation.

PERIODIC ENVIRONMENTS AND PERIODIC HARVESTING
Natural Resource Modeling, 2003 ABSTRACT. We consider autonomous population models under periodic harvesting and population models in periodic environments and seek conditions under which there is an asymptotically stable periodic solution.

The Problem of Periodization in Sufi Studies: The Struggle of Sufism to Become a Discipline Between the Religious Sciences and Metaphysics [PDF]
Nazariyat: Journal for the History of Islamic Philosophy and Sciences, 2016 The periodization of sciences is one of the essential devices of treating a field by specification and tracing the transformations in that field. Nonetheless, it would be hard to speak of robust periodization concerning religious sciences of Islam.

Periodic Modules with Large Periods [PDF]
Proceedings of the American Mathematical Society, 1979 Let G be a nonabelian group of order p 3 {p^3} and exponent p, where p is an odd prime. Let K be a field of characteristic p. In this paper it is proved that there exist periodic KG-modules whose periods are 2p. Some examples of such modules are constructed.
