Diagonal quadratic forms representing all binary diagonal quadratic forms

The Ramanujan Journal, 2017
For a positive integer \(n\), a positive definite integral quadratic form is \(n\)-universal if it represents all positive definite integral quadratic forms of rank \(n\). For example, the quinary quadratic form \(x_1^2+x_2^2+x_3^2+x_4^2+ x_5^2\) is \(2\)-universal, by a classical result of \textit{L. J. Mordell} [Q. J. Math., Oxf. Ser.

Supercongruences and binary quadratic forms

Acta Arithmetica, 2021
Summary: Let \(p > 3\) be a prime, and let \(a,b\) be two rational \(p\)-adic integers. We present general congruences for \(\sum_{k=0}^{p-1}\binom{a}{k}\binom{-1-a}{k}\frac{p}{k+b}\pmod{p^2} \). Let \(\{D_n\}\) be the Domb numbers given by \(D_n=\sum_{k=0}^n\binom{n}{k}^2\binom{2k}{k}\binom{2n-2k}{n-k} \).
