en تخصصي Special پژوهشي Research paper <div style="text-align: justify;">We introduce a subclass k - T US^&lowast;(&alpha;, &thetasym;)of uniformly starlike functions fand study characterization theorem and coefficients estimates. We also define a neighbourhood of a function funder certain assumptions and study this neighborhood related results. We establish results relating to the partial sums of functions belonging to the class k - T US^&lowast;(&alpha;, &thetasym;). These functions are closely linked with the conformal mappings which lead to the growing applications in boundary and eigen-value problems in mathematics and various other fields of science and engineering. This research may also be related with the various<br> known classes already found in the literature.</div> Coefficients estimates, Neighborhood, Integral means, Partial sums. 1 11 http://ijmsi.ir/browse.php?a_code=A-10-6917-1&slc_lang=en&sid=1 Syed Zakar Hussain Bukhari fatmi@must.edu.pk 100319475328460012053 100319475328460012053 Yes Department of Mathematics, Mirpur University of Science and Technology(MUST), Mirpur-10250(AJK), Pakistan Huo Tang thth2009@163.com 100319475328460012054 100319475328460012054 No School of Mathematics and Computer Sciences, Chifeng University, Chifeng 024000, China Farah Manzoor fmhappiness@yahoo.com 100319475328460012055 100319475328460012055 No Department of Mathematics, Mirpur University of Science and Technology(MUST), Mirpur-10250(AJK), Pakistan
