[HTML][HTML] Practical tests for the Schröder equation to have a regularly varying solution
H Farzadfard - Journal of Mathematical Analysis and Applications, 2019 - Elsevier
Abstract Let f: R+→ R+ be an increasing continuous function having no fixed point such that
the differential d:= lim x→ 0+ f (x) x exists and 0< d< 1. In this paper we present practical …
