-
April 19, 2018. Enriched category theory and spectra as enriched functors.
-
April 17, 2018. An introduction to model categories II. I referred to slides from my 2017 Chicago talk.
-

-
April 3 and 5, 2018. Lectures by Dionel Jaime on Yoneda’s 1954 paper on Ext groups and by Keping Huang and Kenneth Plante on material in McCleary related to the Eilenberg-Moore spectral sequence.
-
March 29, 2018. An introduction to spectra.
-
March 27, 2018. Semin Yoo lectured on Milnor’s 1958 paper, The Steenrod algebra and its dual. Here are her slides.
-
March 8, 2018. Two lectures today on the Eilenberg-Moore spectral sequence.
-
March 6, 2018. H-spaces, Hopf algebras and the double loops of the 3-sphere.
