Dr. G. Poonguzali, Marudai, M., Anastassiou, G. A., and Park, C., “Existence of continuous selection for some special kind of multivalued mappings”, Journal of Computational Analysis and Applications, vol. 27, pp. 447-452, 2019.[Abstract]

This paper deals with the existence of continuous selection of a multivalued mapping in product space. Many authors provided existence of continuous map for lower semicontinuous. We provide continuous selection for weakly lower semicontinuous. Rhybinski [9] proved the existence for contraction type mapping. We prove the existence for some general type of mapping different from contraction mapping.

In this paper, we provide some fixed point results using continuous selection given by Poonguzali et al. [15]. Also, using the selection theorem we discusse the existence of fixed point for the product of two multivalued mappings, that is, of the form Ax·Bx. Using those fixed point results, we give the existence of solution for a newly developed differential inclusion.

In this paper, we prove the existence of a common best proximity point for a pair of multivalued non-self mappings in partially ordered metric spaces. Also, we provide some interesting examples to illustrate our main results.
