We defie the icomplete bivariate Fiboacci ad Lucas p-polyomials. I the case x 1, y 1, we obtai the icomplete Fiboacci ad Lucas p-umbers. If x 2, y 1, we have the icomplete Pell ad Pell-Lucas p-umbers. O choosig x 1, y 2, we get the icomplete geeralized Jacobsthal umber ad besides for the icomplete geeralized Jacobsthal-Lucas umbers. I the case x 1, y 1,, we have the icomplete Fiboacci ad Lucas umbers. If x 1, y 1,, 1/, we obtai the Fiboacci ad Lucas umbers.
