....guises in the study of integral equations. From least to most specific these spaces are the vector space, nor reed linear space, Banach space, and Hilber t space. The material in this section is only a superficial overview. For much greater depth, see any introductory text on real analysis [31, 30]. 2.1 Vector Spaces and Function Spaces A vector space, also called a linear space, is a set X along with two operations defined on its elements, addition and scalar multiplication, under which X is algebraically closed. That is, for any x, y E X, and ( E T4, the sum x y and the scalar ....

....that W ffl = W fx j kx Gamma k fflg will be closed in the usual topology and contain an open subset of W. For each (fl 1 ; fl n ) 2 ZZ n , not all fl i zero, let H fl 1 ; fl n = f( 1 ; n ) 2 Wj P n i=1 fl i i = 0g. Since W ffl is closed, the Baire Category Theorem ([22], p. 139) implies that for some ( fl 1 ; fl n ) H fl 1 ; fl n contains an open subset of W ffl (and so, of W) Therefore dim(H fl 1 ; fl n W) dim W. Since W is irreducible, we must have (H fl 1 ; fl n W) W (c.f. 24] p. 54) so W H fl 1 ; fl n ....

STATE SPACE REPRESENTATION 130 Since ffi is independent of B and fi o , the family of curves B is equicontinuous. Theorem 6. 6 (Arzela Ascoli[52]) Let F be an equicontinuous family of real valued functions on a separable space 1 X. Then each subsequence ff n g in F which is bounded at each point (of a dense subset) has a subsequence ff n k g that converges pointwise to a continuous function, the convergence being uniform on each compact ....

....to show that, for any 2 L p , then Z Omega j jjru j k j p Gamma1 dx Z Omega j jjru j j p Gamma1 dx as k 0, passing to a further subsequence if needed. Then, use the structure condition (ii) and the Generalized Dominated Convergence theorem (see Theorem 16, page 89 in [16]) to conclude that F j (x; ru j k ) converges weakly in L p 0 to F j (x; ru j ) Since rv i Gamma ru i k converges L p strongly to rv i Gamma ru i , we have what we wished. We postpone the proof of boundedness of the solutions in Theorem 1.1 to Section 3; see Lemma 3.1 ....
