Title: On addition theorems related to elliptic integrals,
Abstract: This paper provides some explicit formulas related to addition theorems for
elliptic integrals $\int_0^x dt/R(t)$, where $R(t)$ is the square root from a
polynomial of degree 4. These integrals are related to complex elliptic genera
and are motivated by Euler's addition theorem for elliptic integrals of the
first kind.
