On some $D (u^{2})$ -triples and quadruples of triangular numbers

Pavao Radić

We classify all $D (u^{2})$ -triples of triangular numbers whose smallest element is $T_{4 u - 1}$ or $T_{4 u}$ . We study the regularity of $D (N)$ -triples of triangular numbers. We also sh…

Extensions of $D (4)$ -pairs ${a, k a}$ with $k \in {7, 8, 10, 11, 12, 13}$

Marija Bliznac Trebješanin, Pavao Radić

We study the extensibility of $D (4)$ -pairs ${a, b}$ , where $b = k a$ and $k \in {7, 8, 10, 11, 12, 13}$ . Firstly, we show that it can be extended to a $D (4)$ -triple with an element c,…

On extensions of $D (4)$ -triples by adjoining smaller elements

Marija Bliznac Trebješanin, Pavao Radić

This paper examines the problem of obtaining a $D (4)$ -quadruple by adding a smaller element to a $D (4)$ -triple. We prove some relations between elements of observed hypothetical $D…
