About me

I'm a PhD candidate in analysis (harmonic analysis). I have a Master of Science degree in mathematics (analysis).

I am interested in many topics in analysis, but in particular: harmonic analysis, functional analysis, operator theory and special functions.

My email address is jonasteuwen@gmail.com.

I would appreciate it if you would correct my spelling and grammatical errors.

comment Definition of $L^0$ space
@Martin: True, I'll modify that. You want to end up with convergence in probability.

comment The limit of $f_n(x)$
This proof is actually very slick, but grinding out the details (which is done splendidly) requires some tinkering. I guess there are bigger hammers you can hit the convergence with, but this is truly elementary. I like that. +1.

comment Is this a dirac delta function?
Nice post, shows typical problems with distributions and the order (or even kind of) limits.

comment On the regularity of the Laplace equations and tensor products and such
Does the lack of answers imply that my question is too stupid or that there is nobody that can answer it here? If so, would it more appropriate to ask on MO?

comment Multiplicative formula for Fourier transforms
Sure, $x^{-2}$ is integrable right? The only issue is $0$. So add the $1$ and done. Fubini only requires integrability.

comment Why decimal expansion of $e$ has two copies of $1828$
The comment of joriki is making me paranoid. Jasper is onto something.

comment Fourier Series: Integral of a Sum or Sum of Integrals?
@MattN. I don't think so. This is more PDE-like things.
