AB - We introduce the notions of T-Rickart and strongly T-Rickart modules. We provide several characterizations and investigate properties of each of these concepts. It is shown that R is right Σ-t-extending if and only if every R-module is T-Rickart. Also, every free R-module is T-Rickart if and only if $R = Z₂(R_{R})⊕ R^{\prime }$, where R’ is a hereditary right R-module. Examples illustrating the results are presented.
