一类非全纯模形式II:等变迭代Eisenstein积分

A class of non-holomorphic modular forms II : equivariant iterated Eisenstein integrals

Francis Brown

摘要:

在上半平面上引入了一族新的实解析模形式。他们可以说是最简单的一类“混合”版本的模形式的水平之一,并构建了真正的和虚部的迭代积分的全纯爱森斯坦系列。它们形成了一个函数代数,满足许多类似于经典全纯模形式的性质。特别是,他们承认扩展在$q, \overline{q}$和$\log |q|$只涉及有理数和单值多zeta值。这类函数中的第一个非平凡函数是实解析艾森斯坦级数。

英文摘要:

We introduce a new family of real analytic modular forms on the upper half plane. They are arguably the simplest class of `mixed' versions of modular forms of level one and are constructed out of real and imaginary parts of iterated integrals of holomorphic Eisenstein series. They form an algebra of functions satisfying many properties analogous to classical holomorphic modular forms. In particular, they admit expansions in $q, \overline{q}$ and $\log |q|$ involving only rational numbers and single-valued multiple zeta values. The first non-trivial functions in this class are real analytic Eisenstein series.
