Higher order complex symmetric operators and some of their related classes of operators
Abstract
This paper investigates a novel family of complex symmetric operators, drawing
parallels to the well-established (n, m)-normal operators (Alzuraiqi and Patel, in

33(2A):247-251, 2008; Mecheri in Oper Matrices 15(2):615-626, 2021) and
k-quasi-(n, m)-normal operators (Ahmed et al. in Hacet J Math Stat 5(2):326–341,
2021). Through this exploration, we aim to uncover new properties and relationships
within these classes, contributing to the broader understanding of operator theory.
