<Ilya Piatetski-Shapiro> was a <mathematician> whose research linked <analytic number theory>, <representation theory> and <algebraic geometry>. His early work included the distribution of <prime numbers> in special sequences and uniqueness questions for <trigonometric series>. His later work on <automorphic forms> and representations of <Lie groups> helped connect arithmetic questions with <harmonic analysis>.https://mathshistory.st-andrews.ac.uk/Biographies/Piatetski-Shapiro/[Biography, early work and Wolf Prize citation]{ref} These connections are powerful because the same object can carry both arithmetic information and a rich set of symmetries: methods for studying its transformations can then reveal properties of its arithmetic coefficients.
