An introduction in optimality problems with regard to the error, complexity and efficiency. |
| Content |
|
This course approaches the theory of real functions by using linear operators including various methods of generalization as well as the study of the convergence of operators sequences. The rate of convergence is studied and some asymptotic formulas are established. It also surveys their behaviour on subspaces of functions and investigates their major properties.
Moduli of smoothness, K-functionals and summation methods are also presented. The theory is illustrated through Bernstein - type operators, convolution operators and Kanto-rovich and Durrmeyer type generalizations. The course also deals with the probabilistic study of some semigroups of operators. |
