#### Some applications of tangent categories

###### Tsutomu Okano (Illinois Math)

Abstract: The cotangent complex formalism is a useful framework for developing obstruction theoretic tools such as Andre-Quillen cohomology. I will present a theorem that identifies the tangent categories of Cat_S, where S is some symmetric monoidal infinity-category. Some more example applications of this formalism will follow.
