Abstract

Consider the cubic sensor dx = dw, dy = x3dt + dv where w, v are two independent Brownian motions. Given a function φ(x) of the state x let φt(x) denote the conditional expectation given the observations ys, 0 ≤ s ≤ t. This paper consists of a rather detailed discussion and outline of proof of the theorem that for nonconstant φ there cannot exist a recursive finite-dimensional filter for φ driven by the observations.
