The duality in the study of homographic recurrent sequences
Author: Vasile Berinde
Abstract: In this paper we study sequences of real numbers defined by recurrence relations based on homographic functions. To determine the admissible values for the initial term of a homographically recurrent sequence, a dual sequence is attached and studied, which also satisfies a homographic recurrence.

Characterization of the convergent sequences using linear combinations of k succesive terms
Author: Vasile Berinde
Abstract: In this paper convergent sequences of real numbers are related to the convergence of some special sequences formed as linear combinations of k successive terms of the initial sequence.

Polygons having the same center of gravity
Author: Nicolae Mușuroia
Abstract: In this paper we consider sets of polygons constructed so that each polygon of the set has a common side with a given polygon. We analyze the case when the polygons of a set have common gravity centre, by using complex numbers.

On some recurrent sequence
Author: Dan Bărbosu
Abstract: The aim of this paper is to establish necessary and sufficient conditions for some second order linearly recurrent sequences with variable coefficients to be convergent. Several applications are considered.
