Self-concordant function

In optimization, a self-concordant function is a function for which or, equivalently, a function that, wherever , satisfies and which satisfies elsewhere. More generally, a multivariate function is self-concordant if or, equivalently, if its restriction to any arbitrary line is self-concordant. (Wikipedia).
