calculate function from its divizor
Dear François, I'm indeed interested in the script you mentioned in your answer, could you please put the link to the script here? That will be very helpful. Thank you in advance. |

Existence of multidimensional Levy process with dependent structure
I think The Bridge talks about their "book" whose title is "Financial Modelling with Jump Processes" |

Is the Feynman-Kac formula valid for a time-dependent potential
if $c$ is a function of time too, just consider $$Z_t=\exp(-\int_0^tc(s,X_s))ds$$ then you have $dZ_t=-Z_tc(s,X_s)dt$ and the same reasoning applies. |

I don't see how to make further progress, could you give the reference of the book you've mentioned? |

Relationship between the derivative of a matrix and its eigenvalues
Do you have additional information on the $\alpha_i$ or they are of general form? |

Relationship between the derivative of a matrix and its eigenvalues
Sorry for posting this as an answer, I cannot leave comment. Are you sure your matrix is $$[A(k)]_{j\,l}= -\frac{e^{ik|y_j-y_l|}}{4\pi|y_j-y_l|}\, j\neq l$$ and not $$[A(k)]_{j\,l}= -\frac{e^{ik|y_j-y_l|}-1}{4\pi|y_j-y_l|}\, j\neq l$$ If you want to extend some properties of the derivative of a matrix to its eigenvalue, the eigenvectors have to be independent of the derivation variable. |
