A Model for Configuration Spaces of Closed Manifolds

Published .  conf-spaces  math

Last week I was at the Max Planck Institute for the Conference for Young researchers in homotopy theory and categorical structures (which was, by the way, a great conference -- thanks to the organizers), and I gave yet another talk about the…

First Article Accepted!

Published .  operads  paper  swiss-cheese

My paper Swiss-Cheese operad and Drinfeld center has finally been accepted! It is going to appear in the Israel Journal of Mathematics . I've made the few corrections suggested by the referee (the new version is available on the arXiv ), and I'm…

Configuration Spaces Woes

Published .  conf-spaces  paper

I've been neglecting this blog a lot. Juggling research, teaching, organizing a seminar, and a personal life leaves little time for writing articles! (Wait, isn't that the same complaint as last time?) Most prominently I've been spending a lot of…

The Voronov Product of Operads

Published .  math  operads  swiss-cheese

My first real post in a while! It turns out that writing an actual paper (cf. previous blog post) takes a lot of time and effort. Who knew? The Voronov product of operads is an operation introduced by Voronov in his paper The Swiss-cheese operad…

Paper: The Lambrechts–Stanley Model of Configuration Spaces

Published .  conf-spaces  paper

I have uploaded a new preprint, The Lambrechts--Stanley Model of Configuration Spaces , which you can find on arXiv . Here is the abstract: We prove the validity over ℝ of a CDGA model of configuration spaces for simply connected manifolds with…

Young Topologists Meeting 2016

Published .  trip

This week I was at the Young Topologists Meeting ! It's gotten even bigger than two years ago, as there were more than 180 participants this year. The conference was quite interesting, and Copenhagen is a really nice city! The main theme was…

New Domain Name

Published . Updated .  code

Maybe you (I don't know who reads this anyway) haven't noticed, but this blog has a new URL: operad.fr idrissi.eu ! I splurged and got a domain name. The blog is (for now) still accessible via the old GitHub URL, but this may change at some point…

Talk at ETH Zürich

Published .  photo  talk  trip

Last week I was invited by Thomas Willwacher to ETH Zürich for a few days, during which I also had the opportunity to give a talk at the "Talks in Mathematical Physics" seminar. It was a very interesting few days, and I'm very grateful for this…

Infinity-Operads Demystified

Published .  algtop  higher-cat  math  operads

The purpose of this post is to record the definition of ∞-operads and explain why it works like that. For this I'm using Lurie's definition of ∞-operads; there is also a definition by Cisinski--Moerdijk--Weiss using dendroidal sets, about which I…
