I have been searching without success for the the reference:
Aubin T.- Espaces de Sobolev sur les varietes Riemanniennes. Bull. Sc. Math. 100, (1976) 149-173
It is cited in many related works. In particular, I cannot find a discussion of Sobolev spaces on Lipschitz subdomains of compact boundaryless Riemannian manifolds. Every result references the above, which is extremely difficult to find.
Does anyone know where to find it?
Thank you
