Abstract. In this paper, we developed a non-Gaussian Wick calculus based on the theory of hypecomplex systems $L_1(Q,d m(x))$. Using the Delsarte characters $\chi_{n}(x)$, we introduce a $\chi$-Wick product, a $\chi$-Hermite transform on the space of generalized functions $H_{-q}^{\chi}$ and discuss their properties. By means of the usual properties of complex analytic functions, we proved the characterization theorem for $H_{-q}^{\chi}$. Moreover, we setup a framework to study the stochastic partial differential equations driven by $H_{-q}^{\chi}$-processes, and apply this framework to solve the $\chi$-stochastic Poisson equation.
