Rough Weighted Ideal Convergence and Korovkin-Type Approximation via weighted equi-ideal convergence

Tamim Aziz, Sanjoy Ghosal

If $\ddot{I}{‰}_t>{\hat{I}}^2$ for every $t\in \mathbb{N}$ and for some ${\hat{I}}^2>0$, then the sequence $\{\ddot{I}{‰}_t{\}}_{t\in \mathbb{N}}$ represents a weighted sequence of real numbers. In this article, w…
