  2. Ramanujan graph - Wikipedia

    en.wikipedia.org/wiki/Ramanujan_graph

    See Winnie Li's survey on Ramanujan's conjecture and other aspects of number theory relevant to these results. [ 5 ] Lubotzky , Phillips and Sarnak [ 2 ] and independently Margulis [ 6 ] showed how to construct an infinite family of ( p + 1 ) {\displaystyle (p+1)} -regular Ramanujan graphs, whenever p {\displaystyle p} is a prime number and p ...

  3. Ramanujan–Petersson conjecture - Wikipedia

    en.wikipedia.org/wiki/Ramanujan–Petersson...

    The more general Ramanujan–Petersson conjecture for holomorphic cusp forms in the theory of elliptic modular forms for congruence subgroups has a similar formulation, with exponent (k − 1)/2 where k is the weight of the form.

  4. Lafforgue's theorem - Wikipedia

    en.wikipedia.org/wiki/Lafforgue's_theorem

    Lafforgue's theorem implies the Ramanujan–Petersson conjecture that if an automorphic form for GL n (F) has central character of finite order, then the corresponding Hecke eigenvalues at every unramified place have absolute value 1.

  5. Ramanujan's ternary quadratic form - Wikipedia

    en.wikipedia.org/wiki/Ramanujan's_ternary...

    In number theory, a branch of mathematics, Ramanujan's ternary quadratic form is the algebraic expression x 2 + y 2 + 10z 2 with integral values for x, y and z. [ 1 ] [ 2 ] Srinivasa Ramanujan considered this expression in a footnote in a paper [ 3 ] published in 1916 and briefly discussed the representability of integers in this form.

  6. Selberg class - Wikipedia

    en.wikipedia.org/wiki/Selberg_class

    The condition that the real part of μ i be non-negative is because there are known L-functions that do not satisfy the Riemann hypothesis when μ i is negative. Specifically, there are Maass forms associated with exceptional eigenvalues, for which the Ramanujan–Peterssen conjecture holds, and have a functional equation, but do not satisfy the Riemann hypothesis.

    Ford said the 4,000 job cuts, which represent around 2.3% of its total workforce of 174,000, would be primarily in Germany and Britain. The U.S. automaker is the latest - after Nissan, Stellantis ...

  8. Ramanujan's congruences - Wikipedia

    en.wikipedia.org/wiki/Ramanujan's_congruences

    In mathematics, Ramanujan's congruences are the congruences for the partition function p(n) discovered by Srinivasa Ramanujan: (+) (), (+) (), (+) ().In plain words, e.g., the first congruence means that If a number is 4 more than a multiple of 5, i.e. it is in the sequence
