Ramanujan's Identities and Representation of Integers by Certain Binary and Quaternary Quadratic Forms

Alexander Berkovich, Hamza Yesilyurt

We revisit old conjectures of Fermat and Euler regarding representation of integers by binary quadratic form x^2+5y^2. Making use of Ramanujan's_1ψ_1 summation formula we establish…
