摘要：

In this paper we propose a variant of the generalized Schroder paths and generalized Delannoy paths by giving a restriction on the positions of certain steps. This generalization turns out to be reasonable, as attested by the connection with the faces of generalized cluster complexes of types A and B. As a result, we derive Krattenthaler's F-triangles for these two types by a combinatorial approach in terms of lattice paths. (C) 2008 Elsevier Inc. All rights reserved.
