Abstract: In this paper we study Jensen’s inequality under quadratic g-expectation, i.e., the expectation generated by backward stochastic differential equations (BSDEs) with generator of quadratic growth in its component z. In particular, we define a new kind of convexity, the C-convexity, via a second order ODE depending on a real constant C, and we study the relationships between quadratic g-convexity and C-convexity.
