    On \(p\)-measures of asymmetry for convex bodies (English)
    0 references
    This nicely written paper introduces a set of affine invariant measures of asymmetry for a convex body \(K\), \(as_p(K), 1\leq p \leq \infty\), in which the classical Minkowski measure of asymmetry appears as the extreme case (\(p=+\infty\)). Several properties are derived and we mention in particular the following one: \(1 \leq as_p(K) \leq n\) with \(as_p(K)=1\) if and only if \(K\) is centrally symmetric and \(as_p(K)=n\) if and only if \(K\) is a simplex. The author provides also a geometric interpretation of \(as_1(K)\) in terms of a mixed volume of \(K\) and \(-K\).
