A note on arithmetic congruences
Nic Fellini
By analyzing the coefficients of the power series defining the Kubota--Leopoldt -adic -function associated to the non-trivial character of a real quadratic field, we prove a…

On the Second Hardy-Littlewood Conjecture
Bittu Chahal, Ertan Elma, Nic Fellini +2
The second Hardy-Littlewood conjecture asserts that the prime counting function satisfies the subadditive inequality \begin{align*} π(x+y)\leqslant π(x)+π(y) \end{align*} fo…

Congruence relations of Ankeny$\unicode{x2013}$Artin$\unicode{x2013}$Chowla type for real quadratic fields
Nic Fellini
In 1951, Ankeny, Artin, and Chowla published a brief note containing four congruence relations involving the class number of for positive squarefree integers…
