Summary: An asymptotic minimax problem of signal detection for signals from \(l_q\)-ellipsoids with an \(l_p\)-ball removed \((p>2\) or \(q<p<2)\) in a Gaussian white noise is considered. Asymptotically sharp distinguishability conditions and some estimates of the minimax probability of errors of signal detection for ellipsoids with axes \(a_n\asymp n^{-\lambda}\), \(\lambda>0\), are obtained. The proofs use results and techniques developed by Yu.I. Ingster [see the preceding review, Zbl 0935.62054].
