The Barcelona Topology Workshop is the annual meeting of the Grup de Topologia Algebraica de Barcelona. The Spring Session of the Barcelona Topology Workshop 2016 will take place on the 1011th June, 2016, at the CRM in Barcelona (on the UAB campus).


This is the web site of the Algebraic Topology Team in Barcelona (Grup de Topologia Algebraica de Barcelona, 2014SGR42 and Homotopy theory of classifying spaces and function complexes, MTM201342293P).
Our research interests include a variety of subjects in algebraic topology, group theory, homological algebra, and category theory. Here you will find information about us and our common activities. 
Friday's Topology Seminar 20152016 

This semester we will read BensonGreenlees paper "Stratifying the derived category of cochains on $BG$ for $G$ a compact Lie group".
Our aim will be study the results and see if we can generalize them to the $p$compact case. The tentative schedule is the following:
1) February 19th. W. Pitsch. Overview 2) March 4th. L. Carlier. Tensor triangualted categories 3) April 1st. T. Lozano. $p$compact groups 4) April 15th. W. Pitsch. Stratification I 5) April 29th. W. Pitsch Stratification II 6) May 6th. J. Kock Pointfree Topology on Spec R and support I 7) May 13rd. J. Kock Pointfree Topology on Spec R and support II 8) May 20th W. Pitsch Some results on D(R) for R a ring spectrum 9) June 3rd N. Castellana Noetherianity in cohomology 10) July 1st N. Castellana Chouinard's theorem for finite plocal groups and pcompact groups
Date and place: Fridays 12h0013h00, CRM Room A1.
Regular seminar:
Date and Place: July 15th 12h00, CRM room A1 Speaker: Nicolas Ricka (Wayne State University) Title: The stable Picard group of motivic A(1)
Abstract: Let A be the modulo 2 Steenrod algebra, and A(1) be the subalgebra of A generated by the two first Steenrod squares. As the cohomology of the real Ktheory spectrum is A//A(1), the structure of the category of A(1)modules is of particular importance for ko(co)homology computations. In this talk, I will talk about a determination of the Picard group of the stable category of modules over a motivic version of A(1). I will then discuss some possible applications in the A^1stable motivic category, and its version of the connective real Ktheory spectrum.
