Determines determinants of logarithmic coefficients in bounded rotation functions, indicating broader applications.
In this paper, we determine the Second Hankel and Vandermonde determinants of the logarithmic inverse coefficients for the class Rtanh, a class of functions characterized by bounded boundary rotation and defined by a subordination condition involving the hyperbolic tangent function. The Vandermonde determinant has applications in diverse fields such as error-correcting codes, the Discrete Fourier Transform, representation theory, and the quantum Hall effect.
