Some New Paranormed Sequence Spaces and $\alpha-$ Core
  In this study, we define new paranormed sequence spaces by combining a double sequential band matrix and a diagonal matrix. Furthermore, we compute the $\alpha-,\beta-$ and $\gamma-$ duals and obtain bases for these sequence spaces. Besides this, we characterize the matrix transformations from the new paranormed sequence spaces to the spaces $c_{0}(q),c(q),\ell(q)$ and $\ell_{\infty}(q)$. Finally, $\alpha-core$ of a complex-valued sequence has been introduced, and we prove some inclusion theorems related to this new type of core.
