چکیده
|
In this paper, we introduce the concept of generalized -contractivityof a pair of maps w.r.t. another pair. we establish a common fixed point result fortwo pairs of self-mappings, when one of these pairs is generalized -contractionw.r.t. the other and study the well-posedness of their fixed point problem. inparticular, our fixed point result extends the main result of a recent paper ofqingnian zhang and yisheng song.
