This paper characterises the dual of model space K I 1 , where is an inner function, intersected with shifted Hardy space, z H . With this duality result, it then shown that every bounded truncated Toeplitz operator on 2 has a symbol if and only compact which form multiplied by continuous function.

We characterize the compact multiplication operators on a semicrossed product $C_0(X)\times _\phi \mathbb Z_+$ in terms of corresponding dynamical system. also elements this algebra and determine ideal they generate.

This paper investigates the approximation of set-valued functions with compact images (not necessarily convex), by adaptations of the Schoenberg spline operators and the Bernstein polynomial operators. When replacing the sum between numbers in these operators, by the Minkowski sum between sets, the resulting operators approximate only set valued functions with compact-convex images [10]. To obt...
