A Sturm Liouville theorem for quadratic operator pencils
Alim Sukhtayev, Kevin Zumbrun
We establish a Sturm{Liouville theorem for quadratic operator pencils counting their unstable real roots, with applications to stability of waves. Such pencils arise, for example,…

Block-diagonalization of ODEs in the semiclassical limit and vs. stationary phase
Olivier Lafitte, Mark Williams, Kevin Zumbrun
Motivated by issues in detonation stability, we study existence of block-diagonalizing transformations for ordinary differential semiclassical limit problems arising in the study o…
