Despite being such an important factor for individual identity, the Orthodox churches have not been sufficiently studied. In addition, the study of gender in these churches often seems formed by the impression that they do not change. This article therefore explores a seeming static feature, the gendered seating in three Syriac Orthodox parishes in Sweden from the point of view of space and agency
This chapter calls for policy tools to address gentrification and displacement through one of the most recently discussed and complex lenses of gentrification: green and climate gentrification. Those processes are directly related to residential physical and sociocultural displacement and insecure housing conditions - with demonstrated health impacts - among socially or racially underprivileged re
Since the rise of radical geography in the early 1970s, political economy has been crucial in examining the spatial dynamics of capital in economic geography. Marxist and non-Marxist (particularly institutionalist) economic geographers use political economy to challenge non-political economy approaches that ignore the relationship between microeconomic processes and their spatial manifestations an
Cities with limited traditions in cycle planning often look to Northern European cities as role models, adopting their design concepts and infrastructure solutions. However, experience indicates that transferring such designs across different contexts can be challenging. In many cases, cycle paths have been constructed but remain underutilized. This chapter presents the findings of a study examini
This article is about finding the limit set for banded Toeplitz matrices. Our main result is a new approach to approximate the limit set Λ(b), where b is the symbol of the banded Toeplitz matrix. The new approach is geometrical and based on the formula Λ(b) = ∩ρ∊(0, ∞) sp T (bρ), where ρ is a scaling factor, i.e., bρ(t):= b(ρt), and sp(∙) denotes the spectrum. We show that the full intersection ca
Currently, local regulations governing hydrogen installations vary by geographical region and by country, leading to discrepancies in safety and separation distance requirements for similar hydrogen systems. This work carried out in the frame of IEA TCP H2 Task 43 (IEA TCP H2 2022) aims to provide an overview of various methodologies and recommendations established for risk management and conseque
This book attempts to reconstruct elementary physics in full compliance with reason, thus continuing the work of philosophers (experimental and mathematical) throughout the centuries. The unabridged Newton's mechanics is recovered, Gauss intuitions about relational electromagnetism are developed and completed and Schrödingers undulatory quantum theory is reproposed, unifying all three theories in
The symmetric Al-Salam-Chihara polynomials for q > 1 are associated with an indeterminate moment problem. There is a self-adjoint second-order difference operator on 2(Z) to which these polynomials are eigenfunctions. We determine the spectral decomposition of this self-adjoint operator. This leads to a class of discrete orthogonality measures, which have been obtained previously by Christiansen a
We study the spectral properties of a class of Sturm-Liouville type operators on the real line where the derivatives are replaced by a q-difference operator which has been introduced in the context of orthogonal polynomials. Using the relation of this operator to a direct integral of doubly-infinite Jacobi matrices, we construct examples for isolated pure point, dense pure point, purely absolutely
The Stieltjes-Wigert polynomials, which correspond to an indeterminate moment problem on the positive half-line, are eigenfunctions of a second order q-difference operator. We consider the orthogonality measures for which the difference operator is symmetric in the corresponding weighted L2-spaces. Under some additional assumptions these measures are exactly the solutions to the q-Pearson equation
We consider Jacobi matrices whose essential spectrum is a finite union of closed intervals. We focus on Szego{double acute}'s theorem, Jost solutions, and Szego{double acute} asymptotics for this situation. This announcement describes talks the authors gave at OPSFA 2007.
Classical graphical modeling of random vectors uses graphs to encode conditional independence. In graphical modeling of multivariate stochastic processes, graphs may encode so-called local independence analogously. If some coordinate processes of the multivariate stochastic process are unobserved, the local independence graph of the observed coordinate processes is a directed mixed graph (DMG). Tw
