In this document, we study a 3-polygraphic translation for the proofs of SKS, a formal system for classical propositional logic. We prove that the free 3-category generated by this 3-polygraph describes the proofs of classical propositional logic modulo structural bureaucracy. We give a 3-dimensional generalization of Penrose diagrams and use it to provide several pictures of a proof. We sketch...

abstract: fortunately in recent years in iran, semiotics arguments in literature and art study are noticed by researchers. in according to, the denotation and connotation functions in photography are updated and expanded. thus, necessary bases for continuing this argument are available. although denotation and connotation are belong to semiotics area, but in photography, specially critique of p...

This paper explores the relationship between smartphone practices and lifestyle in urban Iran. Recently, the use of smartphones has dramatically been increased in Iran, and this trend is expected to influence users’ lifestyle in the everyday context. Therefore, to test this hypothesis, I follow the notion of “lifestyle” which was advanced by Pierre Bourdieu to offer an analysis of this changing...

It is absurd and without any scientific interest to try to play off DES against EI, as if the question was to know if one method is better than the other in the absolute. All methodological inventions deserve to be tried and tested. But the question is how apposite are they to their object of study. However, Froese and Gould’s article opens a range of issues that are important and interesting. ...

Acknowledgments I would like to thank my three reviewers, Alberto Apos-tolico, Gregory Kucherov, and Irena Rusu for taking time out of their busy schedule to read my dissertation and write a review. I would like also to express my gratitude to Marie-Pierre Béal for being in my committee. A very special thanks goes out to Maxime Crochemore for his continuous support for my work since the beginni...

We prove global stability results of DiPerna-Lions renormalized solutions for the initial boundary value problem associated to some kinetic equations, from which existence results classically follow. The (possibly nonlinear) boundary conditions are completely or partially diffuse, which includes the so-called Maxwell boundary conditions, and we prove that it is realized (it is not only a bounda...
