en تخصصي Special پژوهشي Research paper <div style="text-align: justify;">In this paper, we discuss the inheritance of strict convexity, uniform convexity and local uniform convexity by the quotient spaces of metric linear spaces. We also show that, as in the case of normed linear spaces, completeness is a three- space property in metric linear spaces as well.</div> Metric linear space, Strict convexity, Uniform convexity, Local uniform convexity, Three-space property. 119 126 http://ijmsi.ir/browse.php?a_code=A-10-5391-1&slc_lang=en&sid=1 Shelly Garg shellygarg24@gmail.com 100319475328460010867 100319475328460010867 No Department of Mathematics, DAV University, Jalandhar-144 012, India Harpreet K.
