This work is a continuation of [18,19,26-28]. The concept of weak compatibility between a set-valued mapping and a single-valued mapping of Jungck and Rhoades [19] is used as a tool for proving some ...

For four decades, a quiet boundary in pure mathematics kept a powerful theorem locked inside the safe world of finite quantities. Now a new result known as Sebestyen’s theorem has pushed that boundary ...

The Pythagorean theorem, a cornerstone of mathematics for millennia, provides a method for determining unknown sides in right-angled triangles using the formula a² + b² = c². Its applications extend ...
