Short Description of the Research Theme In this area of researach we try to find or approximate the solution of the operator equations, under certain contractive conditions in several distance spaces. Further, we apply the obtained result to find the gemetrical pattern of the solutions of the different operator equations like differential, integral equaltions and inclusions.
SDGs Covered SDG#1 Quality Education, SDG#9 Industry, Innovation, and Infrastructure
