Abstract

We introduce a concept of a Goldbach factorization graph (GFG) $F_n$, which can be constructed for each even integer $n$ greater than 2. We prove that, if $n$ does not satisfy the binary Goldbach conjecture (BGC), then $F_n$ contains a special source strongly connected component (exceptional autonomous component, EAC). We analyse existence and properties of EACs using deductive and computational approaches. In particular, we prove that there exists exactly one EAC induced by two vertices. Using computer-aided search, we show that for $n \leq 10^8$ there are 6 EACs, each inside a different GFG, and they are located at the relative beginning of the checked range, namely, for $n\in\{128,1718,1862,1928,2200,6142\}$. Using classic graph algorithms, the constraint programming method, and metaheuristic approaches, we have prepared a repository of drawings and some selected properties of the found EACs and GFGs which contain them. The concept of EAC relates to the BGC, but more generally, it represents interesting self-conjugation of prime numbers under a relation which combines addition and multiplication.

On the factorisation of the $p$-adic Rankin-Selberg $L$-function in the supersingular case

Given a cusp form $f$ which is supersingular at a fixed prime $p$ away from the level, and a Coleman family $F$ through one of its $p$-stabilisations, we construct a $2$-variable meromorphic $p$-adic $L$-function for the symmetric square of $F$. We prove that this new $p$-adic $L$-function interpolates values of complex imprimitive symmetric square $L$-functions, for the various specialisations of the family $F$. We use this $p$-adic $L$-function to prove a $p$-adic factorisation formula, expressing the geometric $p$-adic $L$-function attached to the Rankin--Selberg convolution of $f$ with itself as a the product of the $p$-adic symmetric square $L$-function of $f$ and a Kubota-Leopoldt $L$-function. This extends a result of Dasgupta in the ordinary case.

Exceptional poles of archimedean Rankin-Selberg L-functions for irreducible generic representations of GL(n,R)

For irreducible generic representations $π_1$ and $π_2$ of $\operatorname{GL}_n(\mathbb R)$, we prove that the notions of exceptional pole of type $1$ and type $2$ coincide at every level. When both representations are in general position, we use this identification to express the Rankin--Selberg $L$-function $L(s,π_1\timesπ_2)$ in terms of the exceptional $L$-factors attached to the irreducible constituents of their derivatives.
