Period polynomials, derivatives of L-functions, and zeros of polynomialsTools Diamantis, Nikolaos and Rolen, Larry (2018) Period polynomials, derivatives of L-functions, and zeros of polynomials. Research in the Mathematical Sciences, 5 . p. 9. ISSN 2197-9847
AbstractPeriod polynomials have long been fruitful tools for the study of values of L-functions in the context of major outstanding conjectures. In this paper, we survey some facets of this study from the perspective of Eichler cohomology. We discuss ways to incorporate non-cuspidal modular forms and values of derivatives of L-functions into the same framework. We further review investigations of the location of zeros of the period polynomial as well as of its analogue for L-derivatives.
