Abstract: We study elements of second order linear recurrence sequences $$(G_n)_{n= 0}^{\infty }$$(Gn)n=0∞ of polynomials in $${{\mathbb {C}}}[x]$$C[x] which are decomposable, i.e. representable as $$G_n=g\circ h$$Gn=g∘h for some $$g, h\in {{\mathbb {C}}}[x]$$g,h∈C[x] satisfying $$\deg g,\deg h>1$$degg,degh>1.… read more here.

Abstract: Let (fn)n=1∞ be an unbounded sequence of integers satisfying a linear recurrence relation with integer coefficients. We show that for any k ∈ ℕ there exist infinitely many n ∈ ℕ for which 2k +… read more here.

Abstract: We consider a family of linear recurrence sequences [Formula: see text] of order [Formula: see text] whose first [Formula: see text] terms are [Formula: see text] and each term afterwards is the sum of the… read more here.
