We introduce, in the general setting of a measure space endowed with a measurable metric in the sense of N. Weaver, the concentration function. We then extend some results concerning the Gaussian concentration property. In particular, we study relations between this property and transportation type inequalities or logarithmic Sobolev inequalities.
