Generic Cuspidal Points and Their Localization
Luca Dieci, Alessandro Pugliese
In this work we consider generic coalescing of eigenvalues of smooth complex valued matrix functions depending on 2 parameters. We call generic cuspidal points the parameter values…

SVD, joint-MVD, Berry phase, and generic loss of rank for a matrix valued function of 2 parameters
Luca Dieci, Alessandro Pugliese
In this work we consider generic losses of rank for complex valued matrix functions depending on two parameters. We give theoretical results that characterize parameter regions whe…
