Abstract:
This article discusses a new kind of lattice path and in nite lower triangular array
with the given steps. By using lattice path the lower triangular array which is
obtained has the sum of row on its diagonal. The sum solution is found by generating
function of the sum of row Riordan matrix. The sum is proven by using combination
of theorem and proposition of Riordan matrix. Then a combinatorial interpretation
is obtained for the generalized tribonacci and tribonacci-Lucas polynomial sequence.
This article is a review of article of Ramirez and Sirvent [The Electronic Journal of
Combinatorics, 22 (1) (2015)].
