Abstract:
Catalan first observed that the numbers S(m,n), now called the super
Catalan numbers, are integers, but there is still no known combinatorial
interpretation for them in general. Interpretations have been given for
the case m = 2
and for S(m, m + s) for 0 ≤ s ≤ 4. In this paper,
we define the super FiboCatalan numbers
S(m,n)F and the generalized
FiboCatalan numbers. In addition, we give Lucas analogues for both of
these numbers and use a result of Sagan and Tirrell to prove that the
Lucas analogues are polynomials with non-negative integer coefficients.
This proves that the super FiboCatalan numbers and the generalized
FiboCatalan numbers are integers.
