De la Pureté locale à la décomposition
Fouad Elzein, Lê Dung Trang
The decomposition theorem is deduced from local purity.
Du théoréme de décomposition á la Pureté locale
Fouad Elzein, Lê Dung Trang
A new proof of the decomposition theorem is established using a relation with a version of the local purity theorem of Deligne and Gabber adapted to complex algebraic varieties.
Stratified critical points one the real Milnor fibre and integral-geometric formulas
Nicolas Dutertre
Let be the germ of a closed subanalytic set and let and be two subanalytic functions. Under some conditi…
Parabolic automorphisms of projective surfaces (after M. H. Gizatullin)
Julien Grivaux
In 1980, Gizatullin classified rational surfaces endowed with an automorphism whose action on the Neron-Severi group is parabolic: these surfaces are endowed with an elliptic fibra…
TBA type equations and tropical curves
Sara Angela Filippini, Jacopo Stoppa
We revisit the wall-crossing behaviour of solutions to the Thermodynamic Bethe Ansatz type equations arising in a class of three-dimensional field theories, expressed as sums of "i…
Shimura modular curves and asymptotic symmetric tensor rank of multiplication in any finite field
Stéphane Ballet, Jean Chaumine, Julia Pieltant
We obtain new asymptotical bounds for the symmetric tensor rank of multiplication in any finite extension of any finite field $\F_q$. In this aim, we use the symmetric Chudnovsky-t…
