Abstract:

The objective of this paper is to research the transport equations of Rotenberg's model general boundary condition in the growing cell populations in Lp-space (1≤p <+∞). It is shown the transport operator A generates C0 semigroup and  the existece of the eigenvalue, so it is  obtained that the spectrum of the transport operators only consisting of finitely isolate eigenvalues with finite algebraic multiplicities in the trip Γ.

Key words: Rotenbergs model, Transport operators, C0 semigroup, General boundary condition, Eigenvalue
