On Nonlinear Idempotents and Metric Projections in Normed Spaces

Himanshu Kumar, Abdullah Bin Abu Baker, Fernanda Botelho

Let $X$ be a normed linear space. A map $P : X \to X$ is called idempotent if $P^{2} = P$ . In this paper, we introduce some new classes of idempotent maps (linearity is not as…

Generalized idempotents on the space of analytic functions with bounded derivatives

Himanshu Kumar, Abdullah Bin Abu Baker, Fernanda Botelho

Let $X$ be a complex normed space. A map $P : X \to X$ is called idempotent if $P^{2} = P$ . A collection $C = {P_{1}, P_{2}}$ of nonzero distinct orthogonal ($P_1P_2 =…
