In this talk, I will discuss the relation of span categories to various versions of the symplectic category. I will then expose the connection between simplicial objects and algebras in span categories, focusing on the $1$- and $2$-categorical cases to explicate the underlying intuitions. Finally, I will discuss recent work (joint with Ivan Contreras and Rajan Mehta) generalizing this correspondence to algebras with further structure, that is, to commutative and Frobenius algebras.
