 Sep24 awarded Autobiographer Mar13 comment Relations betweens Multizeta Values Thanks for your comment. I should have been more precise. What I meant by the last statement is if they are related modulo some numerical coefficient?

Aug8 comment Which geometric figure (polyhedron) has 15 quadrilateral faces? Very nice! Good to know that such a thing exists even though the name is still a mystery :) Does anyone know that? Aug8 awarded Student Aug8 asked Which geometric figure (polyhedron) has 15 quadrilateral faces? Jul5 comment What's the rule for solving nested sums? Is there a reference to this method you proposed? Thanks! Apr21 comment Let $F(x,y,z) = -c(r/||r||^3)$ be the force resulting from the inverse square law… As they are all equivalent (it says so in the wiki entry!) choose the one you know how to handle. If you want to know what conservative means: read the article. It's implications are explained there very clearly. Apr21 comment Let $F(x,y,z) = -c(r/||r||^3)$ be the force resulting from the inverse square law… You mean you want to show that F is a conservative force. Just check out the wikipedia article about conservatives forces. It'll tell you all you need :) en.wikipedia.org/wiki/Conservative_force Apr21 comment Let $F(x,y,z) = -c(r/||r||^3)$ be the force resulting from the inverse square law… While this is an easy question: what have you done to solve it? Also, isn't that more of a physics.stackexchange question? Apr5 awarded Critic Apr5 comment Integral in $\mathbb R^3$ and $\Gamma$-function Well, there's actually no reference in my derivation to QFT. Just some playing around with integral identities. I just meant that these sorts of integrals appear in QFT loop computations...that's all :) Other than that, it's pretty straightforward maths :) Apr5 awarded Supporter Apr5 awarded Editor Apr5 revised Integral in $\mathbb R^3$ and $\Gamma$-function Typos Apr5 awarded Teacher
