Monodromic Nilpotent Singular Points with Odd Andreev Number and the Center Problem
(Springer, 2022-12-01)
Given a nilpotent singular point of a planar vector field, its monodromy is associated with its Andreev number n. The parity of n determines whether the existence of an inverse integrating factor implies that the singular ...

beta-Scission of thioimidoyl radicals (R-1-N-C-center dot=S-R-2): A theoretical scale of radical leaving group ability
(2007)
A theoretical study of the beta-scission reactions for some thioimidoyl radicals (R-1-N=C-center dot-S-R-2) using a recently introduced homofugality index, nu(center dot) is presented. This index, that was defined as a ...
