Imagining the School of the Future Through Computational Simulations: Scenarios’ Sustainability and Agency as Keywords

open access: yesFrontiers in Education, 2022
Computational simulations are fundamental tools not only for scientific research but also for education. They are frequently used as virtual laboratories to foster students’ understanding of the theoretical concepts that lie at the basis of the simulated

Complications in discourses on near-death experiences [PDF]

open access: yesنشریه پژوهش‌های زبان‌شناسی
The purpose of this article is to find complications in Farsi discourse of Near-Death Experiences (NDE). We first examined the main categories of complications and then compared them in the stories of those who claimed to have near-death experience and ...

Lie group structures on groups of smooth and holomorphic maps on non-compact manifolds [PDF]

open access: yes, 2007
We study Lie group structures on groups of the form C^\infty(M,K)}, where M is a non-compact smooth manifold and K is a, possibly infinite-dimensional, Lie group. First we prove that there is at most one Lie group structure with Lie algebra C^\infty(M,k)

Simple Space-Time Symmetries: Generalizing Conformal Field Theory [PDF]

open access: yes, 2006
We study simple space-time symmetry groups G which act on a space-time manifold M=G/H which admits a G-invariant global causal structure. We classify pairs (G,M) which share the following additional properties of conformal field theory: 1) The stability ...

Exact Evolution Operator on Non-compact Group Manifolds

open access: yes, 1997
Free quantal motion on group manifolds is considered. The Hamiltonian is given by the Laplace -- Beltrami operator on the group manifold, and the purpose is to get the (Feynman's) evolution kernel.

On the analogy between real reductive groups and Cartan motion groups. III: A proof of the Connes-Kasparov isomorphism

open access: yes, 2019
Alain Connes and Nigel Higson pointed out in the 1990s that the Connes-Kasparov "conjecture"' for the K-theory of reduced groupe $C^\ast$-algebras seemed, in the case of reductive Lie groups, to be a cohomological echo of a conjecture of George Mackey ...

Abstract Harmonic Analysis on the General Linear Group GL(n,R) [PDF]

open access: yes, 2014
Consider the general linear group, which is not connected but rather has two connected components, the matrices with positive determinant and the ones with negative determinant. Consider the Iwasawa decomposition of its special linear group. We adopt the

Mean eigenvalues for simple, simply connected, compact Lie groups

open access: yes, 2006
We determine for each of the simple, simply connected, compact and complex Lie groups SU(n), Spin$(4n+2)$ and $E_6$ that particular region inside the unit disk in the complex plane which is filled by their mean eigenvalues.

Geometry of invariant domains in complex semi-simple Lie groups [PDF]

open access: yes, 2007
We investigate the joint action of two real forms of a semi-simple complex Lie group S by left and right multiplication. After analyzing the orbit structure, we study the CR structure of closed orbits. The main results are an explicit formula of the Levi
