One new question. I sincerely apologize to use so much the common ressource. This works perfectly

x,θ,z = SR.var('x θ z')
y = function('y')
x = function('x')
diff(y(x(θ,z)), z)

My question is simply is there a way to substitute $y^\prime(x(\theta,z))$ to $D_0(y(x(\theta,z))$ since $y$ is univariate ? And if this is possible to do the same thing for second order.

I am not sure of the meaning of your question, but I suppose that you want a "more conventional" typesetting of your expression (The D[0]... notation has been adopted for its unanbiguous nature).

This is not a new issue...

As far as I can tell, this cosmetic workaround should do what you mean...
