Abstract
Lawvere theories (also known as algebraic theories) are a categorical presentation-free formulation of algebraic structure (such as that of monoids, groups, rings, etc.). I will introduce and provide intuition for the definition of a Lawvere theory and its models, and discuss a result of Linton establishing a correspondence between Lawvere theories (and their models in Set) and finitary monads on Set (and their algebras).
