Dyadic Steenrod algebra and its applications

Ali S. Janfada, Ghorban Soleymanpour

First, by inspiration of the results of Wood \cite{differential,problems}, but with the methods of non-commutative geometry and different approach, we extend the coefficients of th…

On $θ$ -congruent numbers on real quadratic number fields

Ali S. Janfada, Sajad Salami

Let $K = Q (m)$ be a real quadratic number field, where $m > 1$ is a squarefree integer. Suppose that $0 < θ < π$ has rational cosine, say $cos (θ) = s / r$ with…

On the high rank $π /3$ and $2 π /3$ -congruent number elliptic curves

Ali S. Janfada, Sajad Salami, andrej Dujella +1

Consider the elliptic curves given by $E_{n, θ} : y^{2} = x^{3} + 2 s n x^{2} - (r^{2} - s^{2}) n^{2} x$ where $0 < θ < π$ , $cos (θ) = s / r$ is rational with $0 \leq ∣ s ∣ < r$ and $g cd (r, s) = 1$ . These e…
