June 9th–13th 2008

International Workshop on Mathematical Understanding Univ Paris 7.

An International Workshop on ‘Mathematical Understanding’ organized by Prof. Ivahn Smadja (University Paris-Diderot and REHSEIS) and jointly sponsored by the Département Histoire et Philosophie des Sciences – Université Denis Diderot, REHSEIS and the Ideals of Proof Project.

For more information see: http://www.histnet.cnrs.fr/research/sfhst/spip.php?article217

This workshop was intended to contrive a fruitful confrontation between studies of conceptually rich history of mathematics and themes in the philosophy of mathematics. Taking into account some historical background, notably some of the overarching viewpoints and programs which emerged in the 19th and 20th centuries : (geometrization, algebraization, arithmetization, …), the aim was to shed light on various epistemic, cognitive and logical aspects of mathematical knowledge. Different approaches were studied in the setting of particular historical case studies and then brought into relation to general philosophical questions and approaches involving logical and formal tools.

Talks  in ICTM 2008 International Category Theory Meeting Calais June 22nd-28th 2008

Pedro RESENDE : Part I : Frobenius Objects in Cartesian BiCategories (Report on Joint Work with RFC Walters) plus Part II  : Invertibility and Rubano’s 1972 Theorem :  Monoidal Natural Transformations between Strong Monoidal Functors and their Duals

Taslyn KUSHALIK : On The Continuum Hypothesis in the setting of Topos Theory and Algebaric Set Theory

Aide-memoire/memorandum of short discussion with FWLawvere : How did Dedekind’s conception of the Continuum arise ? Could mathematicss have taken a different turn faced with the so-called “pathological functions” of 19th century Analysis – towards questioning the definition of continuity rather than expanding the notion of function ?

Keywords/threads  : Grothendieck topology ; preservation of coverings under pullback – along what ? arbitrary maps ? or those preserving a smaller class of coverings ? ;  piecewise analytic functions and the program of tame topology;  putting continuity (and cohesion) back into the continua
