It is often useful to replace a function with a sequence of smooth functions approximating the given function to resolve minimizing optimization problems. The most famous one is the Moreau envelope. Recently the function was organized using the Bregman distance h D . It is worth noting that Bregman distance h D is not a distance in the usual sense of the term. In general, it is not symmetric and it does not satisfy the triangle inequality The purpose of the research is to study the convergence of the Moreau envelope function and the related proximal mapping depends on Bregman Distance for a function on Banach space. Proved equivalence between Mosco-epi-convergence of sequence functions and pointwise convergence of Moreau-Bregman envelope We also studied the strong and weak convergence of resolvent operators According to the concept of Bregman distance.

We define Riemann – Banach space and the space conformal to the Euclidean planer space, then we create The necessary and sufficient conditions in order to be Riemann – Banach space conformal to the Euclidean space, then we prove that constant- curvature Riemann – Banach spaces which have are conformal to the Euclidean space. Finally, we create locally, the measurement in constant curvature Riemann –Banach spaces.
In this work we study the convergence of Haar- Series with real monotone coefficients and find the sum of that series using the generalized liner summing mothed. For we use the special classes.
The purpose of the research is to study the Bergman function and Bergman distance to generalize Moreau – Yosida Approximation. To do that we replace the quadratic additive terms in Moreau – Yosida Approximates by more general Bergman distance and s tudy properties of generalized approximation and prove equivalence between epigraph – convergence and pointwise convergence of the generalized Moreau – Yosida Approximation.
The purpose of the research is to study Bergman distance to generalize Lasry – Lions regularization which play important role of theory optimization. To do that we replace the quardatic additive terms in Lasry – Lions regularization by more gene ral Bergman distance (non metric distance), and study properties generalized approximation and proof its continuous as we give a relationship between the solution minimization sets of function and Lions – Lasry Regularization and others properties.
