In the paper we consider the problem of multiple interpolation in a class of functions of a zero order and type not exceeding normal in the upper halfplane of the complex variable. This problem belongs to the class of problems of free interpolation considered initially by A. F. Leont'ev. We find necessary and sufficient solvability conditions for this problem. The found criteria are formulated in terms of the canonical products constructed on knots of interpolation, and in terms of the Nevanlinna measure determined by these knots. The work is a continuation of researches of the first author considered similar problems in classes of analytic functions in the upper half-plane of a nonzero order.
Keywords: zero specified order, divisor, canonical product, Levin condition, Nevanlinna measure.
