Statistical properties of subgroups of free groups
No full textThe usual way to investigate the statistical properties of finitely generated subgroups of free groups, and of finite presentations of groups, is based on the so-called word-based distribution: subgroups are generated (finite presentations are determined) by randomly chosen k-tuples of reduced words, whose maximal length is allowed to tend to infinity. In this paper we adopt a different, though equally natural point of view: we investigate the statistical properties of the same objects, but with respect to the so-called graph-based distribution, recently introduced by Bassino, Nicaud and Weil. Here, subgroups (and finite presentations) are determined by randomly chosen Stallings graphs whose number of vertices tends to infinity. Our results show that these two distributions behave quite differently from each other, shedding a new light on which properties of finitely generated subgroups can be considered frequent or rare. For example, we show that malnormal subgroups of a free group are negligible in the graph-based distribution, while they are exponentially generic in the word-based distribution. Quite surprisingly, a random finite presentation generically presents the trivial group in this new distribution, while in the classical one it is known to generically present an infinite hyperbolic group. <br/
Abstracts Collection -- 25th International Symposium on Theoretical Aspects of Computer Science
No full textThe Symposium on Theoretical Aspects of Computer Science (STACS) is held alternately
in France and in Germany. The conference of February 21-23, 2008, held in Bordeaux,
is the 25th in this series. Previous meetings took place in Paris (1984), Saarbr\"{u}cken (1985),
Orsay (1986), Passau (1987), Bordeaux (1988), Paderborn (1989), Rouen (1990), Hamburg

Preface -- 25th International Symposium on Theoretical Aspects of Computer Science
No full textThe interest in STACS has remained at a high level over the past years. The STACS
2008 call for papers led to approximately 200 submissions from 38 countries. Each was
assigned to at least three program committee members. The program committee held a
2-week long electronic meeting at the end of November, to select 54 papers. As co-chairs
of this committee, we would like to sincerely thank its members and the many external
referees for the valuable work they put into the reviewing process. The overall very high
quality of the papers that were submitted to the conference made this selection a difficult task.
We would like to express our thanks to the three invited speakers, Maxime Crochemore,
Thomas Schwentick and Mihalis Yannakakis, for their contributions to the proceedings.
Special thanks are due to A. Voronkov for his EasyChair software (www.easychair.org)
which gives the organisers of conferences such as STACS a remarkable level of comfort;
to Ralf Klasing for helping us explore the many possibilities of this brilliant software; to
Emilka Bojanczyk for the design of the STACS poster, proceedings and logo; and to the
members of the Organizing Committee, chaired by David Janin.
An innovation in this year's STACS is the electronic format of the publication. A
printed version was also available at the conference, with ISBN 978-3-939897-06-4. The
electronic proceedings are available through several portals, and in particular through HAL
and DROPS. HAL is an electronic repository managed by several French research agencies,
and DROPS is the Dagstuhl Research Online Publication Server. We want to thank both
these servers for hosting the proceedings of STACS and guaranteeing them perennial availability.
The rights on the articles in the proceedings are kept with the authors and the papers
are available freely, under a Creative Commons license (see www.stacs-conf.org/faq.html

Audience, intention, and rhetoric in Pascal and Simone Weil.
No full textThis dissertation examines audience, intention, and rhetoric in the writings of Blaise Pascal and Simone Weil. Despite the differences in historical period, ethnic heritage, sex, and milieux, which separate them, these two writers are astonishingly similar with regard to those for whom they wrote--audience--the subject matter of their writings--intention--and their skilled and self-conscious use of language in addressing their audiences and themes--rhetoric. Each of them wrote scientific or philosophical works, and polemical works, intended for a certain public; each of them then wrote, in the final years of their short lives, long notebook or journal entries, a record of spiritual experience which has since been edifying to others besides themselves. The guiding principle here is the function of language. This means how it works (rhetoric), but also, for what purpose (intention) and for whom (audience). We find many metaphors of function in Pascal and Simone Weil. The motivating concern of this dissertation is how Pascal and Simone Weil articulate, through language, God's response to man's yearnings toward God

A comparative study of form and theology in the works of Flannery O'Connor and Simone Weil
No full textIn this comparative study of the form and theology of Flannery O'Connor and Simone Weil I interrogate how Weil's philosophical writings and her theology illuminate O'Connor's use of both narrative and non-fictional forms, and her Catholicism. The Introduction analyses how Weil's concept of superposed reading provides a new method of approaching both O'Connor, her writings, and O'Connor
studies, and focuses on how such apparently different women interconnect. Chapter One explores how both Weil and O'Connor attempt to write their theologies on the
souls of their readers yet are each subject to constraints imposed by form. Weil's concept of locating equilibrium between incommensurates is discussed, and her
distinctively philosophical approach to fictions and fictionality is used to investigate O'Connor's notion of prophetic fictions and the writer's role. Chapter Two assesses how both writers revivify Christian paradoxes. Weil's monstrous concept of affiiction, and O'Connor's use of the grotesque genre to jolt secular man into an
awareness of the sacred are scrutinised. Chapter Three studies how both writers consider an encounter between God and man is possible through the action of grace. My Conclusion interrogates how Weil's work can deepen our understanding of O'Connor's writings, and examines how successful O'Connor is at realising a truly
Christian literature. I conclude that despite being a writer of powerful fictions, O'Connor can not be totally successful in her mission as writer-prophet because
ultimately fiction escapes orthodoxy

W artykule ukazano myśl o ofierze w życiu i pismach intelektualistki, jak również analogie, które rzucają nowe światło na ofiarę Weil. Jako klucz do interpretacji i zrozumienia ofiary Weil, autorka analizuje myśl Emmanuela Levinasa oraz Józefa Tischnera.The author interprets the sacrifice that Simone Weil filed with itself. The main point of the present article is the assumption that the sacrifice Simone Weil was the most important idea of her life. A thought about the victim is portraying the article in the life and letters of the intellectual, as well as is portraying analogies which are shedding new light on the Weil victim. As the key to interpretation and understanding the her victim, the author is analysing the thought of Emmanuel Levinas and Jozef Tischner.Udostępnienie publikacji Wydawnictwa Uniwersytetu Łódzkiego finansowane w ramach projektu „Doskonałość naukowa kluczem do doskonałości kształcenia”.
