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

Tamim Aziz, Sanjoy Ghosal

If ${\omega }_t>\beta$ for every $t\in \mathbb{N}$ and for some $\beta >0$, then the sequence $\{{\omega }_t{\}}_{t\in \mathbb{N}}$ represents a weighted sequence of real numbers. In this article, we pr…
