A comparison of three recent selection theorems. (English) Zbl 1174.26311
Summary: We compare a recent selection theorem given by V. V. Chistyakov using the notion of modulus of variation, with a selection theorem of K. Schrader based on bounded oscillation and with a selection theorem of L. Di Piazza and C. Maniscalco based on bounded \({\mathcal A},\Lambda \)-oscillation.
