 Apr 20 awarded Popular Question Feb 29 comment Jump discontinuities under uniform convergence This sounds like a home-work problem to me! Feb 28 awarded Notable Question Feb 22 comment Jump discontinuities under uniform convergence What is there in (1). If $f_n$ may or may not have jump discontinuties, then is it necessary that $f$ also may or may not have jump discontinuties? Isn't this trivial? aside another note : number of jump discontinuties of a function in $\mathbb{R}$ is always countable.

My question is (what I want to learn) the solution of the coupled ODE system I have mentioned, and not the Burger's equation itself. Why I am interested is that I can build a computational model which can compute numerically, for any given initial data $u(x,0)$. Jan 27 comment Solving a system of ODE that arose in solving Burgers' equation @LutzL : I am trying to solve in Fourier-Galerkin method, where it is done like this. But the references I read do not tell how the ODE is solved, perhaps thats a well known thing in the field of numerical PDE or CFD, I am trying hard to get references. Jan 27 comment Solving a system of ODE that arose in solving Burgers' equation From what I googled, it seemed to be a coupled ODE. Wonder any ready made solution available?

Dec 15 comment Placing delta's at maxima, Is there any smart equation based expression? Thank you very much @Joonas. That was very helpful. Dec 15 comment Placing delta's at maxima, Is there any smart equation based expression? But I still need to understand from the middle expression, how you got the right most expression where summation removed. It seems to me that you used formula of $\delta(f(t))$, which introduced multiplication by $k''(t)$, but the already existing factor $H(-k''(y))k(y)$, wouldn't that hinder? Request you to exapnd a bit for my understanding. Also it would be nice, if you could comment on expresion for $\Gamma(t)$. Dec 15 comment Placing delta's at maxima, Is there any smart equation based expression? Thanks very much, +1; Couldn't ask for a better expression. It seems very right to me, I never got the idea of composition of functions earlier.
