The Jacobian conjecture and injectivity conditions
Saminathan Ponnusamy, Victor V. Starkov
One of the aims of this article is to provide a class of polynomial mappings for which the Jacobian conjecture is true. Also, we state and prove several global univalence theorems…

Absolutely Convex, Uniformly Starlike and Uniformly Convex Harmonic Mappings
Saminathan Ponnusamy, Anbareeswaran Sairam Kaliraj, Victor V. Starkov
In this paper, we prove necessary and sufficient conditions for a sense-preserving harmonic function to be absolutely convex in the open unit disk. We also estimate the coefficient…
