Formula for the Perimeter of a spherical triangle?
Thanks for your help! This is a nice formula. In my understanding this formula doesn't work for triangles with any of its lengths $\ell_i>\pi$. Do you agree or am I missing something? |

Boundary regularity of Dirichlet Eigenfunction on bounded domains
Thank you very much! @Christian: Why should there be a problem? Do you have an exceptional situation in mind? |

construction of heat kernels for non-compact manifolds with boundary
Did you find an answer to your question in meanwhile? I'm wondering, if one can construct the dirichlet heat kernel for unbounded domains with boundary this way (e.g. unbounded domains in euclidean space). |

Existence of the Dirichlet heat kernel for arbitrary open subsets?
@Chrisitan: Thank you! What do you mean by $e^{t\Delta}$? In my experience this symbol occurs in two situations. First in the context of 'continuous functional calculus'. And second in the theory of 'strongly continuous semigroups'. Maybe all of them correspond to the same operator, but I'm not sure. I would be very glad, if you can explain it to me? |

How to evaluate the wiener measure of sets?
Thank you very much for your help! I have to think some time about your approach and probably will tell you whether it helps. |

How to evaluate the wiener measure of sets?
@Nate Eldredge: I want to know the measure of the set G (which I wrote down above), which is quite explicit. Don"t you think so? |

@Kjos-Hanssen: Why do you mean the set can't be a Borel set? |

@Martin Hairer: Thank you very much for your comment. I will consider the construction via Kolmogorov soon. But I'm not a probabilist. |
