Abstract

I will explain recent developments about the formality or non-formality of the Swiss-Cheese operad and its potential uses. In particular, I will present joint work with R. V. Vieira about the non-formality of Voronov’s version of the Swiss-Cheese operad, as well as our current work in progress about a conjectural reinterpretation in terms of symmetric Massey products.
