Geodesics on 2-surfaces with pseudo-Riemannian metric: singularities of changes of signature
A. O. Remizov University of Porto
Abstract:
Smooth 2-surfaces with pseudo-Riemannian metric are considered, that is, ones with quadratic
form in the tangent bundle that is not positive-definite. Degeneracy points of the form are said to be parabolic.
Geodesic lines induced by this pseudo-Riemannian metric in a neighbourhood of typical parabolic points are considered, their phase portraits are obtained and extremal properties are investigated.
Bibliography: 23 titles.
Keywords:
pseudo-Riemannian metric, geodesic lines, singular points, resonances, normal forms.
