The concept of statistical convergence is one of the most active areas of research in the field of summability. Most of the new summability methods have relation with this popular method. In this paper, we introduce the concept of double Iθ -statistical-τ -convergence which is a more general idea of statistical convergence. We also investigate the ideas of double Iθ -statistical-τ -boundedness and double Iθ -statistical-τ -Cauchy condition of sequences in the framework of locally solid Riesz space endowed with a topology τ and investigate some of their consequences. © 2013 Savas; licensee Springer.
