Further, we discuss subordination and majorization results for the associated families. Few known and several new consequences are established.eninfo:eu-repo/semantics/closedAccessRegular functionsFekete-Szego functionalquasi-subordinationmajorizationsubordinationFekete-Szego functional for regular functions based on quasi-subordinationArticle10.22075/ijnaa.2021.23420.253711152110513WOS:000875194800011N/A
