Abstract

This paper is a slightly modified version of the talk I gave at the Dennisfest. After some reminiscences about how things were in the good old days, including how Dennis’ work and mine were somewhat transverse ;-) I will review and update my ancient, unpublished (now arXived) paper with Mike Schlessinger on the deformation theory of rational homotopy types. Then, I will return briefly to another transverse intersection of my work with Dennis’.

Keywords

deformation theory, rational homotopy theory, classifying space, moduli space, $L_{\infty}$-structure
