New statements of difficulties arose lately tough thorough ana lysis. observe, to start with, the statements of difficulties utilizing adjoint equations which progressively grew to become a part of our lifestyles. Adjoint equations are able to convey clean rules to varied difficulties of latest know-how in response to linear and nonlinear tactics. They grew to become a part of golden fund of technological know-how via quantum mechanics, thought of nuclear reactors, optimum keep watch over, and eventually helped in fixing many difficulties at the foundation of perturbation process and sensitivity thought. to stress the real function of adjoint difficulties in technological know-how one should still point out 4-dimensional research challenge and answer of inverse difficulties. This variety of difficulties contains firstly difficulties of world weather adjustments on our planet, kingdom of setting and defense of environ ment opposed to toxins, maintenance of the biosphere in stipulations of full of life progress of inhabitants, in depth improvement of undefined, and so forth. All this required advanced examine of enormous platforms: interac tion among the ambience and oceans and continents within the thought of weather, cenoses within the biosphere laid low with toxins of traditional and anthropogenic starting place. difficulties of neighborhood and worldwide perturbations and types sensitivity to enter info sign up for into universal advanced system.

However, we can call off the assumption and obtain 1 Jp = jp(cp,x)cpdx, o 1 Jp = j f(x)cp*dx o . 16), Jp will remain as a linear functional of a solution to the adjoint problem 1 Jp = JJ
7) is the sought-for functional. 8) We thus obtain a dual formula for definition of one functional. 8) happens to be more useful in many complex problems, especially if the source function J(x) changes in the variations of the problem while the operator and boundary conditions do not. 7; IJ ~: We can compute this functional using the formula J = OA JJ(x)
11). 13), we obtain two equivalent formulas to compute the functional Jp : Jp =j 1 o p(x)cpdx, Jp =j 1 f(x)cp*dx 0 We have regarded the function p as independent of the solution cp until now. However, we can call off the assumption and obtain 1 Jp = jp(cp,x)cpdx, o 1 Jp = j f(x)cp*dx o . 16), Jp will remain as a linear functional of a solution to the adjoint problem 1 Jp = JJ
