Eisenstein series fourier expansion

Using the above recurrence relation, all higher E 2 k can be expressed as polynomials in E 4 and E 6. For example:. Many relationships between products of Eisenstein series can be written in an elegant way using Hankel determinants , e. Garvan's identity. Srinivasa Ramanujan gave several interesting identities between the first few Eisenstein series involving differentiation.

These identities, like the identities between the series, yield arithmetical convolution identities involving the sum-of-divisor function. Other identities of this type, but not directly related to the preceding relations between L , M and N functions, have been proved by Ramanujan and Giuseppe Melfi , [2] [3] as for example.

Automorphic forms generalize the idea of modular forms for general Lie groups ; and Eisenstein series generalize in a similar fashion. One can then associate an Eisenstein series to every cusp of the Hilbert—Blumenthal modular group. From Wikipedia, the free encyclopedia. Series representing modular forms. Not to be confused with Eisenstein sum.

About this article Cite this article Vinogradov, A. The modular invariants g 2 and g 3 of an elliptic curve are given by the first two Eisenstein series:. The article on modular invariants provides expressions for these two functions in terms of theta functions.

Any holomorphic modular form for the modular group can be written as a polynomial in G 4 and G 6. Specifically, the higher order G 2 k can be written in terms of G 4 and G 6 through a recurrence relation. Then the d k satisfy the relation. Here, n k is the binomial coefficient. The d k occur in the series expansion for the Weierstrass's elliptic functions :.

Then the Fourier series of the Eisenstein series is. In particular, one has. The summation over q can be resummed as a Lambert series ; that is, one has. When working with the q -expansion of the Eisenstein series, this alternate notation is frequently introduced:.

In fact, we obtain the identities:. Using the q -expansions of the Eisenstein series given above, they may be restated as identities involving the sums of powers of divisors:.

Similar techniques involving holomorphic Eisenstein series twisted by a Dirichlet character produce formulas for the number of representations of a positive integer n ' as a sum of two, four, or eight squares in terms of the divisors of n.

Using the above recurrence relation, all higher E 2 k can be expressed as polynomials in E 4 and E 6. For example:.
