I am a 40+ math amateur who enjoys the classic proofs and is especially interested in understanding generalizations of Bertrand's Postulate.
36 Generalizing Ramanujan's proof of Bertrand's Postulate: Can Ramanujan's approach be used to show a prime between $4x$ and $5x$ for $x \ge 3$ apr 10 '13
11 Does it follow that $(n!)^n$ divide $(n^2)!$ feb 4 '15
10 Is there a function that can be subtracted from the sum of reciprocals of primes to make the series convergent jul 4
8 Is it possible to generalize Ramanujan's lower bound for factorials that he used in his proof of Bertrand's Postulate? apr 13 '13
6 Generalizing complex numbers: Is there a mathematical system isomorphic to 3 dimensional space? jan 13
