Title: Neutral stochastic partial functional integro-differential equations driven by G-Brownian motion Authors: Bingjun Wang Hongjun Gao Abstract: In this article, we define the Hilbert-valued stochastic calculus with respect to G-Brownian motion in G-framework. On that basis, we prove the existence and uniqueness of mild solution for a class of neutral stochastic partial functional integro-differential equations driven by G-Brownian motion with non-Lipschitz coefficients. Our results are established by means of the Picard approximation. Moreover, we establish the stability of mild solution. An example is given to illustrate the theory. Submitted December 14, 2018.
