 Mar11 awarded Favorite Question Jul21 awarded Nice Question Jul2 awarded Curious Jan2 comment Eigenfunctions of the Helmholtz equation in Toroidal geometry Dear Shuhao, thanks for your answer, although my thanks is quite late. Thanks for your argumentation and calculation. Most valuable, though, seems to be the reference to Boyer et al., Nagoya Math. J. 60 (1976) you provided and therein, P. Morse and H. Feshbach, "Methods of Theoretical Physics", a must-have. Dec31 awarded Nice Question May11 awarded Popular Question Oct21 awarded Yearling Oct6 awarded Autobiographer Apr28 comment A Projection Problem in Functional Analysis - Uniqueness of a Solution I wanted to know if a certain approach I was using in some paper (arxiv.org/abs/1107.4934) was unique :) Apr28 accepted A Projection Problem in Functional Analysis - Uniqueness of a Solution Apr28 comment A Projection Problem in Functional Analysis - Uniqueness of a Solution Thank you oenamen for your answer! Dec7 comment Stochastic interpretation of Einstein Equations Dear @Jon, thank you very much for your answer! Since I think the generalization to a four-dimensional Pseudo-Riemannian manifold is challenging, I appreciate your insightful two dimensional approach very much. Greets Dec7 accepted Stochastic interpretation of Einstein Equations Oct21 awarded Yearling May21 awarded Nice Question May10 awarded Nice Question May2 comment Is there a definitive guide to speaking mathematics? Very nice question @Michael and very nice idea for a program! If you can come up with something, this will greatly help a lot of people! Greets Feb27 answered Vector multiplication with scalars Jan21 comment A Projection Problem in Functional Analysis - Uniqueness of a Solution @JonasT: Thank you for your thoughts! By the dual I mean it in the sense as in the Dirac notation, en.wikipedia.org/wiki/Bra-ket_notation . What you meantion in your second comment is exactly the problem. If $\alpha$ and $\beta$ are just constants (as I might not have pointed out very direct), taking the Fourier transform and dividing, they will be functions... This is one thing I am puzzled with :) Greets Jan20 asked A Projection Problem in Functional Analysis - Uniqueness of a Solution
