....dt = Thus S 1 I m strongly as ff 0. Similarly, S 0 strongly. Since Gamma 1 , we have S 1 : Defining K = Gamma Gamma) we have that K is compact, since K is compact and K is self adjoint (using Exercise 18, page 127, Gohberg and Goldberg [9]) We will use the following (Exercise 6.6 , page 136, Weidmann [18] Sublemma 3.5 Suppose that Tn , T 2 L(V ; W) and that Tn T strongly. Let S 2 L(U ; V) be compact. Then TnS TS uniformly. 1 K K uniformly, using the Sublemmas 3.4 and 3.5. But KS 1 = S , and (S K ( K) ....

....4.2 for a limit result on such sequences that is a consequence of theorem 4.1 on nested Brownian motions. This result provides the main argument in the proof of our theorem 5.1 in section 5. 2. Preliminaries In the concluding section 5 we need some elementary facts on matrix norms, see e.g. [4]. We denote Euclidean norms by . If A is an n m matrix, we write #A# = sup Ax : x # R m , x = 1 . We will use the fact that this norm has the following properties (I denotes the identity matrix, B is another matrix such that AB is defined and x # R m ) #I# = 1, #A T ....

....a from V into V. A representation of Gamma is a homomorphic mapping of Gamma to GL(V) When V is of dimension n, each linear transformation a : V V can be represented by a square matrix of order n, whose elements a ij are complex numbers and are given by a ij = ha(e j ) e i i [10], e i , i = 1; n being a basis for V. Thus, the group GL(V) is the group of invertible square matrices of order n. This also means that the representation (U ) is a square matrix of order n. The dimension n is also called the degree of the representation. If we are given two ....

....function of the process. Also, we show that the desired expansion can be found by employing the Karhunen Loeve theorem. Finally, we discuss the optimality (in some sense) of using the stated approach. The background material on Hilbert spaces mainly follows the presentations contained in [6, 8, 16]. The material on the Karhunen Loeve expansion can be found in [2, 10, 16] The discussion of coherent structures is based mainly on the treatment by Sirovich in [12] Discussion of various aspects of this subject can also be found in [1, 3, 4, 7, 11, 13, 14, 15] 3.1 Hilbert Spaces and Orthogonal ....

....of the process. Also, we show that the desired expansion can be found by employing the Karhunen Loeve theorem. Finally, we discuss the optimality (in some sense) of using the stated approach. Much of the the material in this section is based on the treatment of the theory of Hilbert spaces in [9] [2], 5] and [3] 3.1 Hilbert Spaces and Orthogonal Expansions A Hilbert space H is a vector space over IR or I C together with an inner product Delta; Delta which is complete as a metric space. The norm is defined as kOEk = p OE; OE for OE 2 H and the metric is defined as d(OE; ....

....of all possible reloading patterns, so the loading pattern is unknown in advance. This makes all coefficients k 1 (x; 0) variable, resulting in a system of equations with a large number of nonlinear and nonconvex terms. In this paper, we make use of a model based on the theory of Green functions [4, 9, 11]. The key idea of this approach is that we can write the solution of differential equation (17) with boundary conditions (18) 19) in implicit form: OE(x; t) 1 k eff t Z X G(x; x 0 )k 1 (x 0 ; t) Omega 1 a Omega s )OE(x 0 ; t) dx 0 (21) where the Green function G(x; x 0 ....
