Dr. Mahenthiram Arunmaran is a Senior Lecturer at the University of Jaffna, Sri Lanka, specializing in pure mathematics. His research primarily focuses on complex analysis, particularly harmonic measure and its distribution functions in simply and multiply connected domains. He also contributes to bitopological spaces, exploring concepts such as semiconnectedness and compactness. His work combines rigorous theoretical analysis with applications in geometric function theory. Overall, his research advances mathematical understanding in complex and topological structures.
