Coefficient characterization for certain classes of univalent functions
(Bulletin of the Belgian Mathematical Society - Simon Stevin, 2009)
Necessary and sufficient coefficient conditions are established for certain
classes of analytic functions to be univalent in the unit disk. In addition,
characterizations and convolution results are established for these ...
Polynomial Interpolation Problem for Skew Polynomials
(Applicable Analysis and Discrete Mathematics, 2007)
Let R = K[x;δ] be a skew polynomial ring over a division ring K. We introduce the notion of derivatives of skew polynomial at scalars. An analogous definition of derivatives of commutative polynomials from K[x] as a function ...

Two methods of quantum well profile optimization for maximal nonlinear optical susceptibilities
(Physical Review B, 2001)
Two different approaches for the optimization of the quantum well profile are proposed and discussed. One is the multiparameter procedure, based on the inverse spectral theory (IST) and supersymmetric quantum mechanics ...
