چکیده
The Steklov averages (Steklov or integral means) are used in approximation theory of functions different aspects. This article concerns the by using operator cosine function framework. offers a counterpart translation operator, which forms basic concept for modulus continuity and some processes as well. We will show that allows to define very general an abstract Banach space. properties these generalized appear be quite similar trigonometric approximation.

Preconditioning the Poincaré-Steklov operator by using Green's function
This paper is concerned with the Poincaré-Steklov operator that is widely used in domain decomposition methods. It is proved that the inverse of the Poincaré-Steklov operator can be expressed explicitly by an integral operator with a kernel being the Green’s function restricted to the interface. As an application, for the discrete Poincaré-Steklov operator with respect to either a line (edge) o...
متن کاملOn the Complex Symmetry of the Poincaré-steklov Operator
Employing Lorentz reciprocity and the Stratton-Chu formalism it is shown that the Poincaré-Steklov or admittance operator can be interpreted as a complex symmetric operator mapping the tangential electric field (instead of the equivalent magnetic current) onto the equivalent electric current. We show that the pertinent block Calderón projectors can be reformulated as operators with a block Hami...
متن کاملOn Positivity for the Biharmonic Operator under Steklov Boundary Conditions
The positivity-preserving property for the inverse of the biharmonic operator under Steklov boundary conditions is studied. It is shown that this property is quite sensitive to the parameter involved in the boundary condition. Moreover, positivity of the Steklov boundary value problem is linked with positivity under boundary conditions of Navier and Dirichlet type.

On Operator-valued Cosine Sequences on Umd Spaces
A two-sided sequence (cn)n∈Z with values in a complex unital Banach algebra is a cosine sequence if it satisfies cn+m + cn−m = 2cncm for any n,m ∈ Z with c0 equal to the unity of the algebra. A cosine sequence (cn)n∈Z is bounded if supn∈Z ‖cn‖ < ∞. A (bounded) group decomposition for a cosine sequence c = (cn)n∈Z is a representation of c as cn = (b n +b−n)/2 for every n ∈ Z, where b is an inver...
