Knowledge and understanding are quite different. Only understanding can lead to being, whereas knowledge is but a passing presence in it. (G.Gurdjieff)

comment Probability of a trajectory in Markov processes
@Did I appreciate (again) your knowledge of what is better to do in other people's time. Which is a manifestation clearly antithetical to arrogance. All the best.

comment Probability of a trajectory in Markov processes
@Did My mathematical contribution to this page is obviously null, I wouldn't waste much of your precious mathematical time to assess such an evident fact. Thanks for drawing useful conclusions and putting it in a personal way, again. As I see that you don't like suggestions on the way you interact on math.SE, I will stop it here. Good luck with your smart-aleck disposition ;)

comment Probability of a trajectory in Markov processes
@Did Well, I imagine you took this thing too personal. I am sorry to disappoint you, but I won't go through your provocative questions, because, again, it isn't about you that this site and this thread and this world are all about. Anyway, until the point where you started giving lessons and unasked-for opinions about what math.SE is the site for, this thread was interesting and useful.

comment Probability of a trajectory in Markov processes
@Did Well, I won't go through what has been said. But, simply, please - do not give anyone lessons about what math.SE is the site for. Or about what is a loss or time or not. I didn't find reading this q&a a loss of time, and there will surely be other people thinking like me. Reading your unexplainably arrogant comment, that was indeed a loss of time and a huge let-down.

comment Space-dependent diffusivity and finite-differences
Found the mistake, in the explicit part I used $u_{j+1}-u_j$ instead of $[u_{j+1}-u_{j-1}]/2$!

comment Space-dependent diffusivity and finite-differences
Usually, to test it in the simplest case, I use $D(x)=x$ or $D(x)=1-x$, to see how it behaves going to both boundaries.

@Nick Could you help me trying to explicit the calculation in components of with the index notation? Because I cannot see it, sorry.

$(\boldsymbol{p}\cdot\nabla\boldsymbol{p})_\alpha=p_\beta\partial_\beta p_\alpha$

No, I simply meant the application of $P$ to those terms: $P(\boldsymbol{p}\cdot\nabla\boldsymbol{p})$
