An extension of HessKato Theorem to Elliptic Systems and Applications
It is well known that the HessKato Theorem, concerning the first
eigenvalue and the first eigenfunction of the second order elliptic
equation, plays an important role in nonlinear analysis. This theorem
now is extended to a class of elliptic systems based on the Maximum
Principle due to Sweers. Applications to bifurcations and multiple
critical points for systems are studied. In particular the critical
group characterization of mountain pass point is also extended to
systems.
Refreshments will be served in Math Annex Room 1115, 3:15 p.m.
