Abstract Consider the subspace $${{{\mathscr {W}}}_{n}}$$ W n of $$L^2({{\mathbb {C}}},dA)$$ L 2 ( C , d A )<...

In the present work, by making use of Gegenbauer polynomials, we introduce and study a certain family λ -pseudo bistarlike id="M2"> biconvex functions with respect to symmetrical points defined in open unit disk. We obtain estimates for initial coefficients solve Fekete–Szeg id="M3"> o ...

In this article, we introduce and study a new family P?(?,?,k,?,?,?,r) of normalized analytic ?-pseudo-starlike bi-univalent functions by using the Horadam polynomials, which is associated with certain convolution operator defined in open unit disk U. We establish bounds for |a2| |a3|, where a2, a3 are initial Taylor-Maclaurin coefficients. Furthermore, obtain Fekete-Szeg? inequality class P? (...

Particle filtering is probably the most widely accepted methodology for general nonlinear applications. The performance of a particle filter critically depends on choice proposal distribution. In this paper, we propose using wrapped normal distribution as angular data, i.e. data within finite range (-&#x03C0;,&#x03C0;]. We then use same method to derive density filter, in place standard ...
