Km ÞÃ 5 K1Ã 1 ? 17, we have ðK1 \ ? \ Km ÞÃ 5 K1Ã 1 ? 1 KmÃ : Since KiÃ ; i 5 1; . . 21, K1Ã 1 ? 1 KmÃ is also a polyhedral cone. 14. A polyhedral set can be represented as a sum of a polytope and a polyhedral cone. Conversely, the sum of any polytope and a polyhedral cone is a polyhedral set. & Let us introduce an additional coordinate x0 and consider a system of homogeneous inequalities hx; xÃk i 2 x0 β k # 0; k 5 1; . . ; l; x0 \$ 0 ð1:24Þ 24 Approximation and Optimization of Discrete and Differential Inclusions Clearly, the set of solutions to this system is a polyhedral cone in ℝn11, the elements of which can be represented as follows:  0 X  0 m x x 5 λj j ; λj \$ 0; ð1:25Þ xj x j51  0 is an (n 1 1)-dimensional vector in ℝn11.

Remember that setting x0 5 1, a solution to Eq. 22) is obtained from a solution to Eq. 24). Consequently, every solution of Eq. 22) can be represented in the form X X λj xj 1 γ j yj ; λj \$ 0 ð1:27Þ x5 jAI 0 and X γ j 5 1; jAI1 γ j \$ 0; jAI1: ð1:28Þ jAI1 Note that the first term on the right-hand side of Eq.

Finally we show that (3)-(1). 20. If f is a closed convex function and f(x0) is finite at x0, then f(x) . 2N everywhere. & Above, it was shown that if f takes the value 2N, then f(x) 5 2N for all xAri dom f. 4, if xAdom f then (1 2 λ)x 1 λx1Ari dom f for all λ and x1Ari dom f. , f(x) 5 2N for all xAdom f. Thus, if f is finite at even one point, then f(x) . 23. If f is a convex function, then the function f defined by epif 5 epi f f ðxÞ 5 inf fx0 : ðx0 ; xÞAepi f g x0 is said to be the closure of f.
