Let $(X, \tau)$ and $(Y, \sigma)$ be topological spaces in which no separation axioms are assumed, unless explicitly stated if $\mathcal{I}$ is an ideal on $X$.Given a multifunction $F\colon (X, \tau)\rightarrow (Y, \sigma)$, $\alpha,\beta$ operators \tau)$, $\theta,\delta$ proper $X$. We introduce study upper lower $(\alpha, \beta,\theta,\delta,\mathcal{I})$-continuous multifunctions.A said to...

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...
