# Mahler problem

A conjecture in the metric theory of Diophantine approximation (cf. Diophantine approximation, metric theory of) stated by K. Mahler [1]: For almost-all (in the sense of the Lebesgue measure) numbers the inequality

has a finite number of solutions in polynomials of degree not exceeding . Here , is a natural number and is the maximum modulus of the coefficients of . An equivalent formulation is: For almost-all the inequality

has a finite number of solutions in integers ( is the distance from to the nearest integer).

Mahler's problem was solved affirmatively in 1964 by V.G. Sprindzhuk [2]. He also proved similar results for complex and -adic numbers, and also for power series over finite fields.
