Abstract:
Using a
type index theorem, we show the existence and multiplicity
of solutions for the sublinear ordinary differential equation
with suitable periodic or boundary conditions.
Here
is a linear positive selfadjoint operator,
is a parameter between two egienvalues of this operator,
and
is the gradient of a potential function.
