Boundary value problems for quasielliptic equations in a half-space.
This paper deals with parabolic-elliptic chemotaxis systems with the sensitivity function and the growth term under homogeneous Neumann boundary conditions in a smooth bounded domain. Here it is assumed that
We study hypersurfaces of complex projective manifolds which are invariant by a foliation, or more generally which are solutions to a Pfaff equation. We bound their degree using classical results on logarithmic forms.
