Euler factors of equivariant $L$ --functions of Drinfeld modules and beyond

Cristian D. Popescu, Nandagopal Ramachandran

In \cite{FGHP}, the first author and his collaborators proved an equivariant Tamagawa number formula for the special value at $s = 0$ of a Goss--type $L$ --function, equivariant with…

Integer-valued o-minimal functions

Neer Bhardwaj, Raymond McCulloch, Nandagopal Ramachandran +1

We study $R_{an, e x p}$ -definable functions $f : R \to R$ that take integer values at all sufficiently large positive integers. If $|f(x)|= O\big(2^…
