independently rediscoveredRogers-Ramanujan Identities
Historically connected to Rogers, Ramanujan and later Schur.
historically associatedRogers-Ramanujan Continued Fraction
The continued fraction has historical connections to Rogers and Schur as well as Ramanujan.
collaborativeHardy-Ramanujan Asymptotic Formula
A collaboration with G. H. Hardy giving the growth of p(n).
collaborativeHardy-Ramanujan Theorem
A collaboration with G. H. Hardy giving the growth of p(n).
collaborativeHardy-Ramanujan Circle Method
Hardy-Ramanujan Circle Method is catalogued as a method in Partition Theory.
historically associatedHardy-Ramanujan Number

historically associatedLandau-Ramanujan Constant
The Landau-Ramanujan theorem is primarily due to Landau, while Ramanujan obtained related ideas.
historically associatedRamanujan-Soldner Constant
The constant was first discovered by Soldner; its Ramanujan association is historical and nomenclatural.
