Materials and Methods:
 In this paper I will study an approximation in real contra-continuous functions space starting from providing a best element of kind compact set symbol by where is numbers .
 Results:
 Also described function (as continuous functions) also, was able to get example (where it very difficult example) approximate Bernstein operator. 
 CONCLUSION:
 He...

We consider the space of weakly almost periodic functions on a transformation semigroup (S, X , ?) and show that if X is a locally compact noncompact uniform space, and ? is a separately continuous, separately proper, and equicontinuous action of S on X, then every continuous function on X, vanishing at infinity is weakly almost periodic. We also use a number of diverse examples to show ...

We decompose time-varying beta for stock into beta for continuous systematic risk and beta for discontinuous systematic risk. Brownian motion is assumed as nature of price movements in our modeling. Our empirical research is based on high-frequency data for stocks from Tehran Stock Exchange. Our market portfolio experiences 136 days out of 243 trading days with jumps which is a considerable rat...
