Abstract

Let B T 4 l denote a subclass of bounded turning functions connected with a four-leaf-type domain. The goal of the study is to probe into the bounds of coefficients | b 6 | , | b 7 | , | b 8 | , the bounds of the logarithmic coefficients, and the third-order determinants | H 3 , 1 | , | H 3 , 2 | , | H 3 , 3 | for the functions in this class.
