Kirill Kopotun

Kirill Kopotun is a Professor in the Department of Mathematics at the University of Manitoba, where he has held a faculty position since at least 1995. His research focuses on approximation theory, particularly in polynomial and spline approximation, moduli of smoothness, and convex/constrained approximation. He actively contributes to numerical analysis, linear algebra, and partial differential equations.

• Research Themes: Uniform/pointwise estimates for polynomial approximation, applications of Jacobi weights, shape-preserving approximation, k-monotone functions
• Collaborations: Extensive co-authorship with D. Leviatan, I. A. Shevchuk, and others in approximation theory.

Publications span 2019–2015, emphasizing shape-preserving approximation, Jacobi-weighted approximation, and moduli of smoothness. His work appears in journals like Constructive Approximation, Journal of Approximation Theory, and Ukrainian Mathematical Journal.
