A note on the invariants of the -functions

Jerzy Kaczorowski, Alberto Perelli

We explain the exact meaning of a statement we made in a previous paper on invariants, namely that a complex-valued function of the data of the functional equation of an -functi…

Multiple standard twists of -functions

Jerzy Kaczorowski, Alberto Perelli

The standard twist of -functions plays a fundamental role in the Selberg class theory. It is defined as an absolutely convergent Dirichlet series and admits meromorphic continua…

-functions of degree and conductor : underlying ideas and a generalisation

Jerzy Kaczorowski, Alberto Perelli

We present a streamlined account of a recent theorem on the classification of the -functions of degree 2 and conductor 1 from the extended Selberg class. We also present a more…

On the invariants of L-functions of degree 2, I: twisted degree and internal shift

J. Kaczorowski, A. Perelli

This is the first part of a series of papers where the behaviour of the invariants under twist by Dirichlet characters is studied for -functions of degree 2. Here we show, under…

Twists by Dirichlet characters and polynomial Euler products of L-functions, II

J. Kaczorowski, A. Perelli

In a previous paper we proved that if an -function from the Selberg class has degree , its conductor is a prime number and is weakly twist-regular at all primes…

Twists by Dirichlet characters and polynomial Euler products of L-functions

J. Kaczorowski, A. Perelli

We prove that suitable properties of the twists by Dirichlet characters of an L-function of degree 2 imply that its Euler product is of polynomial type.
