WebFeb 1, 2014 · It is obvious that, when a = b = 1, the numbers (a n + b n a n) / (b n + 1) (featured implicitly in Conjecture 1.2 and in Theorem 2.1) reduce to the Catalan numbers C n. There are various q-analogues of the Catalan numbers. See Fürlinger and Hofbauer [10] for a survey, and see [11], [17], [16] for the so-called q, t-Catalan numbers.
