Abstract

An operator TT from a vector lattice EE into a normed lattice FF is called unbounded σ\sigma-order-to-norm continuous whenever xnuo0x_{n}\xrightarrow{uo}0 implies Txn0\| Tx_{n}\|\rightarrow 0, for each sequence (xn)nE(x_{n})_n\subseteq E. For a net (xα)αE(x_{\alpha})_{\alpha}\subseteq E, if xαun0x_{\alpha}\xrightarrow{un}0 implies Txαun0Tx_{\alpha}\xrightarrow{un}0, then TT is called an unbounded norm continuous operator. In this manuscript, we study some properties of these classes of operators and their relationships with the other classes of operators.
