Civil engineers use trig functions, including sine, cosine and tangent, to determine the structural integrity of a building and to figure out how wind, water and other weather conditions will ...

In this paper the Ellis-Gohberg identity and its 2 × 2 block matrix generalization are put into an abstract algebraic setting inspired by the band method. As an application we obtain asymmetric ...

Hypergeometric functions occupy a central role in mathematical analysis by encapsulating a diverse class of series that extend many classical functions. Equally, identities involving harmonic ...
