Coefficient inequalities for pseudo subclasses of analytical functions related to Petal type domains defined by error function

Abstract

Pseudo is a force applied on a function to show the positive or negative effect of it on a class of function defined. The paper aims to investigate the coefficient inequalities for pseudo subclasses of analytical functions related to Petal type domains defined by error function. The early few coefficient bounds were obtained and relevant connection to Fekete-Szegö inequalities have also been derived. The results are new and several other results can be deduced easily from the main findings.
