en عمومى General پژوهشي Research paper In the present manuscript, for four weakly compatible mappings in pairs, some theorems using expansion mappings have been established in C^&lowast;-algebra valued metric space. Also, we proved the theorems using (E.A.) property and (CLR) property. The proved results are the extension and generalization of several results available in metric spaces. To support the findings, suitable examples are also discussed.<br> &nbsp; Common fixed points, (E.A.) property, (CLR) property, Weakly compatible mappings, C*-algebra valued metric space. 177 196 http://ijmsi.ir/browse.php?a_code=A-10-2881-2&slc_lang=en&sid=1 Rishi Dhariwal rishidhariwal51@gmail.com 100319475328460012363 100319475328460012363 No Department of Mathematics, Lovely Professional University, Phagwara, 144411, India Deepak Kumar deepakanand@live.in 100319475328460012364 100319475328460012364 Yes Department of Mathematics, Lovely Professional University, Phagwara, 144411, India
