For this purpose by generalizing the definitions and results of Cichoń et.al. we develop weak partial derivatives double integrability and the mean value results for double integrals on time scales. DeBlasi measure of weak noncompactness and Kubiaczyk’s fixed point theorem for the weakly sequentially continuous mappings are the essential tools to prove the main result. © 2020 Elsevier B.V.
