Half-inverse spectral problems for Sturm--Liouville operators with singular potentials
Rostyslav O. Hryniv, Yaroslav V. Mykytyuk
Half-inverse spectral problem for a Sturm--Liouville operator consists in reconstruction of this operator by its spectrum and half of the potential. We give the necessary and suffi…

Structure groups and holonomy in infinite dimensions
Jean-Pierre Magnot
In this article, we give a theorem of reduction of the structure group of a principal bundle P with regular structure group G. Then, when G is in the classes of Lie groups defined…
