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.

On the regularity of the Laplace equations and tensor products and such Alright - thanks. Indeed, this is what I figured since I asked the question. But then I was wondering 'how bad' this could be - as in a splitting in a good and a bad part. Different question so I'll accept this. |

On the regularity of the Laplace equations and tensor products and such Alright, I seem to be totally misunderstanding things, so I have written how I think it is (but first: lunch). (I'll look at your edit later). |

On the regularity of the Laplace equations and tensor products and such In any case, I have rewritten it slightly. I do not want people to assume I am that stupid that I think tensor spaces are that trivial. |

On the regularity of the Laplace equations and tensor products and such @WillieWong I will rewrite it if you still think it is a 'logical fallacy' after my comment! |

On the regularity of the Laplace equations and tensor products and such Oops - logical fallacy is for me more like a error in verbal reasoning -. Anyway, I meant to say that it is a dense set in the tensor product. That is, a Schauder basis. Is that not true? When we separate we can find sequences of basis functions and then we construct the basis for the solution space as a Schauder basis. |

Does there exist a diagonal dominance concept for integral kernels? On every inner product space every self-adjoint operator $P$is positive if for all non-zero $u$ we have $\langle Pu, u \rangle > 0$. |

Does there exist a diagonal dominance concept for integral kernels? @SimenK. But, I do not see understand why my decomposition would not be the way to proceed. Self-adjointness amounts to real eigenvalues and so on. |

Does there exist a diagonal dominance concept for integral kernels? So, is the question about the positivity of Hilbert-Schmidt operators? Hit it with the spectral theorem to decouple your kernel in that case. |

Growth $\beta X\setminus X$ of a Banach space $X$ Yes, thank you for the link. I had something like that in mind - Topologically dualize a test function space and sqeeuze the Banach space in between. |
