I am a mathematical physicist working on:
• Constructive quantum field theory.
• Rigorous renormalization group methods.
• Mathematical statistical mechanics.
• Combinatorics related to Feynman diagrams and cluster expansions.
• Classical invariant theory, and applications of the classical symbolic method to problems in algebraic geometry and representation theory.

Positivity of coefficients of a power series
I agree with Igor. Another ref which might also be useful is the paper arxiv.org/abs/1301.2449 by Scott and Sokal. |

Multivariate analogue of Vandermonde determinant
do you know if there is any paper in the literature which tries to find explicit formulas in terms of these SL invariants? |

Fubini for distributions which are not measures?
How do you define F(u,v)? 1/(1-ux-vy)^3 is not a test function. Also the definition of zeta times rho just needs the Nuclear Theorem. |

Flags of varieties
This reminds me of higher adeles introduced by Beilinson and Parshin. You should be able to get some references by searching these keywords. |

Why A. Weil considered elimination theory to be eliminated?
I wouldn't say "the use of elimination theory in intersection theory led to contradictions". Whatever mistakes or contradictions happened, they are not to be imputed to the theory itself but to the sloppiness of its users. |

Old books still used
@Al-Amrani: but then Abhyankar said one should eliminate eliminators of elimination theory. |
