Abstract
In this paper we define and characterize the class $(V_{2}^{\sigma},V_{2}^{\sigma})$ and establish a core theorem, where $V_{2}^{\sigma}$ is the space of $\sigma$-convergent double sequences $x = (x_{jk})$. We further determine a Tauberian condition for core inclusion and core equivalence.
