Abstract
This paper concerns He's Homotopy Perturbation Method (HPM) which has been applied to solve some nonlinear differential equations. In HPM, at first, we construct a homotopy that satisfies ... Read MoreA proof of the Cauchy--Schwarz inequality from the change of reference frame
Volume 3, Issue 1 , February 2021, , Pages 46-47
Abstract
Inspired by [1] a proof of the Cauchy--Schwarz inequality is given by considering the transformation between two different inertial reference frames. Read MoreNotes on the stability of multimixed additive-quartic mappings
