Birkhoff theory
George David Birkhoff (March 21, 1884 – November 12, 1944) was an American mathematician best known for what is now called the ergodic theorem.

It is well known that algebraic theories are equivalent to finitary monads on $\\mathbf{Set}$. In this paper, we generalize this phenomenon to locally finitely presentable categories using …

One of the core assumptions of knowledge space theory (KST; Doignon and Falmagne, 1985, Doignon and Falmagne, 1999) is that the answer of a subject to an item can be dichotomously classified as correct or incorrect.This assumption appears to be very well suited for the classical field of application of KST, namely the …
