On free stochastic processes and their derivatives

We study a family of free stochastic processes whose covariance kernels K may be derived as a transform of a tempered measure σ . These processes arise, for example, in consideration of non-commutative analysis involving free probability. Hence our use of semi-circle distributions, as opposed to Gaussians. In this setting we find an orthonormal basis in the corresponding non-commutative L 2 of sample-space. We define a stochastic integral for our family of free processes.
