Faculty

Dr. N S Gopal is currently working as a Assistant Professor in Presidency College, Bangalore. He received his Ph.D. degree in Mathematics from Birla Institute of Science and Technology Pilani Hyderabad. His research area expertise is in Nabla Fractional Calculus and Nonlinear Analysis. He has worked with the fractional Nabla operator and introduced the fractional Nabla Hilfer operator along with a few important properties of the same. He has worked on various results for existence, uniqueness and existence of positive solutions for fractional difference equations. He has published eleven research papers in highly reputed international journals. He has also presented his research works at various national and international conferences. To his credit, he has qualified both CSIR-JRF 2017 and GATE in 2018.
