| Research Abstract |
An E-polynomial is mapped to a modular form. We observed the obtained modular forms in genus 1. Originally E-polynomials are introduced as a counterpart of Eisenstein series and we found similar properties as Eisenstein series. The obtained modular forms have zeros on the circle of radius 1 in the fundamental region and those zeros have the so-called separation property. However, they are not proved and are expected to be clear in our subsequent research.
