Abstract: We present a compactness criterion in ideal spaces of vector-valued functions. In the case of real functions, the criterion gives a precise formula for the measure of non-compactness. In the Lebesgue-Bochner spaces $L_p(\R^n,U)$ the result can be interpreted as a Riesz compactness criterion and generalizes a theorem of Orlicz and Szufla.

Keywords: riesz compactness criterion, Krasnoselski{\u\i} compactness criterion, ideal spaces, K{ö}the spaces, Banach function spaces, spaces of measurable functions, vector-valued functions

Classification (MSC2000): 46E30, 46E40, 45N10, 46G10
