comment How to approximate the bounding region of a 2d differentiable mapping locally?
Thanks, I used a this package to triangulate the set and apply $f$ on the vertices and then get a Convex Hull of the mapped points. It works ok so far.

comment Asymmetric random walk with unequal step size other than 1.
Still, it is not trivial. I still need to solve high degree polynomials equation for hitting probability. For mean hitting time, it is trivial.

the issue is, when $a$ is large, it is not so simple to solve the equations

comment How to solve this inhomogeneous recurrence difference equation?
I updated my question as I am only interested in the positive solutions which are not infinity. So far I can only find one for the example case
