Résumé :
I will describe black-hole solutions in five-dimensional gravity with a negative cosmological constant and a self-interacting scalar field. The geometry is asymptotically logarithmically anti-de Sitter in the UV. A Hawking-Page phase transition occurs if and only if the IR behavior of the dilaton potential is associated to a confining gauge theory. I will illustrate the properties of the black-hole solutions and of the phase transition for a generic monotonic dilaton potential. The transition is holographically dual to the confining/deconfining phase transition of a 4d theory closely matching pure Yang-Mills, both at zero and finite temperature.
