Does Rankin-Selberg convolution preserve primitivity?
Call $L$-function any element of an L-rig (see Are there infinitely many L-rigs? for a definition). Suppose $F$ and $G$ are two primitive L-functions. Is $F\otimes G$ itself primitive? If yes, does ...

Does this particular L-series built from L-functions of prime degree define an L-function?
Throughout this question, I call 'L-function' any automorphic L-function belonging to the Selberg class.
Suppose $ (F_i)_{(i>0)} $ is a sequence of L-functions with $ F_i $ of degree $ p_i $ ...

Known degrees of L-functions F and G whose Rankin-Selberg convolution is an L-function
Calling '$L$-function' any automorphic $L$-function belonging to the Selberg class, what are the known $L$-functions $L(s,F)$ and $L(s,G)$ of respective degrees $d$ and $d'$ such that the Rankin-...

Rankin-Selberg convolution and product of degrees
As I'm kinda obsessed with the Selberg class and because of the general converse conjecture, I'm still trying to get a rough idea of what automorphic representations and their L-functions as well as ...

Can the isometry group of the set of zeros of an L-function $F$ be used to make $F$ automorphic?
I'm still trying to understand the notion of automorphic (L-)function. Due to my lack of knowledge of the subject, this question may appear pretty vague and therefore may not be suitable for MO. I ...
