In this talk I generalize a result of Behrend-Fantechi and Baranovski-Ginzburg to the 1-shifted cotangent bundle of a smooth scheme over the complex numbers. More precisely, I show how twisted cotangent bundles arise as derived intersection of Lagrangians inside the 1-shifted cotangent bundle, and how quantizations of the twisted cotangent bundles arise as derived tensor products of quantized Lagrangians.

The American Mathematical Monthly has published over fifty papers on the Gamma function, factorials, or Stirling's formula.* In this talk I review (some of!) what's been said, identify some surprising lacunae, and give some easy new results. Some of this work was joint with Jonathan M. Borwein.

*One of the papers won its author, Philip J. Davis, the Chauvenet Prize in 1963. Another paper's author, Manjul Bhargava, won the 2014 Fields Medal. Other notable authors include Richard Askey, Bruce Berndt, and Walter Rudin.

We will discuss some basic properties of the quasicategory of spaces, presenting in particular the quasicategorical analog of theYoneda embedding.
