We study the extremal volume of central hyperplane sections of complex
$n$-dimensional $l_p$-balls with $0 p\le 2.$ We show that the minimum corresponds to hyperplanes orthogonal to vectors $\xi =(\xi ^1,\mathinner {\ldotp \ldotp \ldotp },\xi ^n)\in {{\mathbb C}}^n$ with $|\xi ^1|=\mathinner {\ldotp \ldotp \ldotp }=|\xi ^n|$, and the maximum corresponds to hyperplanes orthogonal to vectors with only one non-zero coordinate.
Keywords:
