Symbol: EisensteinE —

E_{k}\!\left(\tau\right)

— Normalized Eisenstein series

The normalized Eisenstein series

E_{k}\!\left(\tau\right)

is defined for even integers

k \ge 2

and

\tau

in the upper half-plane.

The functions

G_{k}\!\left(\tau\right)

and

E_{k}\!\left(\tau\right)

are the same up to a normalizing factor.

Definitions:

Fungrim symbol	Notation	Short description
`EisensteinE`	$E_{k}\!\left(\tau\right)$	Normalized Eisenstein series
`EisensteinG`	$G_{k}\!\left(\tau\right)$	Eisenstein series
