Manno G. Metrics admitting projective symmetries (abstract)

Speaker: Giovanni Manno

Title: Metrics admitting projective symmetries

Abstract:
A classical problem is to classify and find normal forms of metrics admitting projective symmetries, i.e., vector fields whose local flow sends (unparametrized) geodesics into (unparametrized) geodesics. In this seminar we discuss this problem for 2 and 3 dimensional metrics and, time permitting, also its complex analogue.
