We present coincidence points results for multivalued f- nonexpan- sive mappings in the setting of nonstarshaped domain of q-normed space which is not necessarily a locally convex space. As application, an invariant approximation result is also obtained. Our results improve and extend the results of Bano, Khan and Latif (1), Hussain (4), Latif and Tweddle (7), Rhoades (11), Sahab, Khan and Sessa (13), Shahzad (14) and Singh (15) in the setting of nonstarshaped domain.
