Abstract :Convergence of real valued sequences especially statistical convergence is very popular subject in Mathematical Analysis. Also, it has got a lot of characterizations in literature. In this paper, we are going to define $\lambda$-statistical supremum and $\lambda$-statistical infimum for real valued sequence $x=insert ignore into journalissuearticles values(x_n);$. After giving some basic properties of these new notations, then we are going to find a necessary and sufficient condition for to existence of λ-statistical convergence of the sequence $x=insert ignore into journalissuearticles values(x_n);$.
Keywords : Statistical supremum infimum, Statistical convergence, Natural density
