In this paper we study the eigenvalues and eigenfunctions of metric measure manifolds. We prove that any eigenfunction is C1, α at its critical points and C∞ elsewhere. Moreover, the eigenfunction corresponding to the first eigenvalue in the Dirichlet problem does not change sign. We also discuss the first eigenvalue, the Sobolev constants and their relationship with the isoperimetric constants. 2000 Mathematics Subject Classification: 47J05, 47J10, 53C60, 58E05, 58C40.
