摘要：
The aim of this paper is to study (regional) fractional Poincare type inequalities on unbounded domains satisfying the finite ball condition. Both existence and non existence type results on regional fractional inequality are established depending on various conditions on domains and on the range of s is an element of (0, 1). The best constant in both regional fractional and fractional Poincare inequality is characterized for strip like domains (omega -> Rn-1), and the results obtained in this direction are analogous to those of the local case. This settles one of the natural questions raised by K. Yeressian in [Asymptotic behavior of elliptic nonlocal equations set in cylinders, Asymptot. Anal. 89, (2014), no 1-2].
