Abstract : We study the properties of black holes with cosmological constant in the framework of geometrothermodynamics.
We consider in particular the case of the Schwarzschild-anti-de-Sitter black hole, and show that the
corresponding fundamental equation is a generalized homogeneous function only if the cosmological constant is assumed to
be a thermodynamic variable. We analyze the geo- metric properties of the equilibrium space and show that the presence of
the cosmological constant changes drastically the stability properties and the phase transition structure of the black hole.
