Some properties like Laplace transform, integral and operational representation, fractional calculus operators of this family are investigated. Also, we compute Fourier transform for this new set and discover a new family of finite biorthogonal functions with the help of Parseval's identity. Further, in order to have semigroup property, we modify this finite set by adding two new parameters and construct fractional calculus operators. Thus, integral equation and integral operator are obtained for the modified version.eninfo:eu-repo/semantics/closedAccessFinite Biorthogonal PolynomialKonhauser PolynomialMittag-Leffler FunctionFractional OperatorLaplace TransformFourier TransformFinite Bivariate Biorthogonal I-Konhauser PolynomialsArticle10.1016/j.cam.2025.1171062-s2.0-105017634579
