Abstract Let ϵ: N→ R be a parameter function satisfying the condition ϵ (k)+ k+ 1> 0 and let T ϵ:(0, 1]→(0, 1] be a transformation defined by T ϵ (x)=− 1+(k+ 1) x 1+ ϵ (k)− k ϵ (k) x for x∈(1/(k+ 1), 1/k]. Under the algorithm T ϵ, every x∈(0, 1] is attached an expansion, called generalized continued fraction expansion with parameters by F. Schweiger [3]. Define the sequence {k n (x)} n≥ 1 of the partial quotients of x by k 1 (x)=⌊ 1/x⌋ and k n (x)= k 1 (T ϵ n− 1 (x)) for every n≥ 2. It is clear that under the condition satisfied by the parameter function ϵ, k n+ 1 (x)≥ k n (x) for all n≥ 1. In this paper, we consider the size of the set given by E ϵ (α):={x∈(0, 1]: k n+ 1 (x)≥ k n (x) α for all n≥ 1} for any α≥ 1. We show that dim H E ϵ (α)={1 α, when ϵ (k)≡ ϵ 0 (constant); 1 α− β+ 1, when ϵ (k)∼ k β and α≥ β≥ 1; 1, when ϵ (k)∼ k β and α< β. where dim H denotes the Hausdorff dimension. The first result generalizes a result of J. Wu [5] who considered the case when ϵ≡ 0 (ie, Engel expansion).
