comment Taylor expansion to show that for Stratonovich stochastic calculus the chain rule takes the form of the classical one
@0.5772156649... Indeed, didn't know that :-)

comment Algorithm for finding all roots of linear Diophantine equation with finite solution space
Thank you, I upvoted and accepted your answer. Well, too bad... Could you do me a favour a let the program run not for $17$ but for $16$ $a$-terms, all else being equal (i.e. starting from $16a_1$ up to $a_{16}$) - Thank you again.

comment Algorithm for finding all roots of linear Diophantine equation with finite solution space
I thought that it would be easier to use this additional condition to prune the solutions to the first equation but I didn't imagine that there were so many solutions to it...

I have an additional condition, but I thought it would make things more complicated: $$a_1+a_2+\dots+a_{16}+a_{17}=0$$

comment Algorithm for finding all roots of linear Diophantine equation with finite solution space
@Abstraction: I can't imagine that there are $10^{17}$ solutions because the equation seems quite "rigid". My "feeling" is that there must be a lot less. But perhaps I am wrong.

@Abstraction: I have two concrete cases: $c=-200$ and $c=-40$.

comment Variance of a special random walk
@Did: You asked for the bigger context of this problem and I posted another question here: math.stackexchange.com/questions/1309230/… - This time I really tried hard to give all the necessary information, let's see if this is sufficient for your critical eye ;-)

comment Connections between the solution of simple ordinary equation, normal distribution and heat equation
Do you see a connection between the heat equation and the above ode? Both have the normal distribution as a solution, is this a coincidence?

comment Connections between the solution of simple ordinary equation, normal distribution and heat equation
Thank you. Ok, I understand that but doesn't it show that the normal distribution is the simplest and in a way most natural unimodal distribution?

Well, no, I think it is still helpful! Please keep it! It would be great if you could find the connection between the diffusion equation and the above ode :-)
