Abstract: In this paper we study a class of parabolic initial boundary value problems relative to an operator
whose the prototype is
u_t−Ze^W(x)div(∇uZ^(−1)e
^(−W(x))) = g,
where W(x) is a smooth function and Z is a
constant. We obtain an estimate of the solution comparing it with the solution to a problem relative to the
operator
u_t− 1/ϕ(x) (u_(x_1)ϕ(x))_(x_1)=G,
where ϕ(x) is the density of Gauss measure, G is a function related
to g and the data depend only on the time variable and the first space variable.

Abstract: We prove some uniqueness results for weak solutions to some classes of nonlinear parabolic equations with homogeneous Cauchy-Dirichlet boundary condition. Precisely we consider operators with a first order term or operators which have just principal part depending on u .

Abstract: In this paper we study a Dirichlet problem relative to the equation Lu = g \phi - (f_i \phi)(x_i), where L is a non linear elliptic operator with a lower-order term whose ellipticity condition is given in terms of the function \phi(x), the density of the Gaussian measure.
