Application of the Leray-Schauder alternative to nonlinear singular operator equations
Altun, Ishak; Koca, Kerim (Pergamon-Elsevier Science Ltd, 2009)In this paper, we study the problem of existence of solution of nonlinear singular integral equations of the form {w(z) = Phi(z) + T(G)F (., w (.), h (.)) (z) h(z) = Phi'(z) + Pi(G)F (., w (.), h (.)) (z), z is an element ... -
A boundary value problem for nonhomogeneous Vekua equation in Wiener-type domains
Koca, Kerim; Çelebi, Okay (2007)In this article we take the nonhomogeneous Vekua equation w_{\overline{z}} Aw B\overline{w} F; z \in D subject to the conditions Rew \partial D\varphi , \varphi \in C{\alpha}(\partial D) Imw (z_0) c_0 , z_0 \in overline{D}. ... -

A note on maximal commutators and commutators of maximal functions
Agcayazi, Mujdat; Gogatishvili, Amiran; Koca, Kerim; Mustafayev, Rza (Math Soc Japan, 2015)In this paper maximal commutators and commutators of maximal functions with functions of bounded mean oscillation are investigated. New pointwise estimates for these operators are proved.
