Research Area: Approximation Theory, Functional Analysis, Dynamical System
Rishikesh Yadav is working as a Postdoctoral Research Fellow under the mentorship of Prof. Alexandre Mauroy in the Department of Mathematics, at Namur Institute for Complex Systems (naXys), University of Namur, Belgium. He did his Ph.D. in Approximation Theory (by using Positive Linear Operators for approximating the functions) from the Department of Mathematics and Humanities, Sardar Vallabhbhai National Institute of Technology Surat, Gujarat, India in 2021 under the guidance of Prof. Vishnu Narayan Mishra and Dr. Ramakanta Meher.
His current area is primarily lies in the intersection of Approximation Theory, Dynamical Systems, and Koopman Operator Theory.
