Bp. Rynne, THE HAUSDORFF DIMENSION OF SETS ARISING FROM DIOPHANTINE APPROXIMATION WITH A GENERAL ERROR FUNCTION, Journal of number theory (Print), 71(2), 1998, pp. 166-171
Let m, n be positive integers and let psi:Z(n) --> R be a non-negative
function. Let W(m, n; psi) be the set [GRAPHICS] The Hausdorff dimens
ion of W(m, n; psi) is obtained for arbitrary non-negative functions p
si, with no monotonicity assumptions. (C) 1998 Academic Press.
