nLab quantum dilogarithm

The quantum dilogarithm was discovered by physicist Anatole Kirillov and by Ludwig Fadeev and Kashaev. The latter also discovered a fundamental pentagon relation for the quantum dilogarithm, which is an analogue of the classical Roger’s identities and makes a connection to the current subject of cluster transformations. Cf. also classical dilogarithm.
