    Ramanujan's constant is the transcendental number [5], which is an almost integer: [6] = … +. This number was discovered in 1859 by the mathematician Charles Hermite. [7] In a 1975 April Fool article in Scientific American magazine, [8] "Mathematical Games" columnist Martin Gardner made the hoax claim that the number was in fact an integer, and that the Indian mathematical genius Srinivasa ...

    A Heegner number is a number n such that Q(√ −n) is an imaginary quadratic field of class number 1. Topics referred to by the same term This disambiguation page lists articles associated with the title Heegner .

  5. Stark–Heegner theorem - Wikipedia

    en.wikipedia.org/wiki/Stark–Heegner_theorem

    In number theory, the Heegner theorem [1] establishes the complete list of the quadratic imaginary number fields whose rings of integers are principal ideal domains. It solves a special case of Gauss's class number problem of determining the number of imaginary quadratic fields that have a given fixed class number.

    en.wikipedia.org/wiki/Gelfond's_constant

    The number e π √ 163 is known as Ramanujan's constant. Its decimal expansion is given by: e π √ 163 = 262 537 412 640 768 743.999 999 999 999 250 072 59... (sequence A060295 in the OEIS) which suprisingly turns out to be very close to the integer 640320 3 + 744: This is an application of Heegner numbers, where 163 is the

    en.wikipedia.org/wiki/19_(number)

    19 is the sixth Heegner number. [50] 67 and 163, respectively the 19th and 38th prime numbers, are the two largest Heegner numbers, of nine total. The sum of the first six Heegner numbers 1, 2, 3, 7, 11, and 19 sum to the seventh member and fourteenth prime number, 43. All of these numbers are prime, aside from the unit.
