The matrices on the right-hand side of the above inequality, 

The relations (8.14) will be checked for each summand // (XM). Hence we fix n during the proof. 

Once this claim is proved, we can see that P[i, j] and P j, i] cancel out as follows  

Thus our remaining task is to compute the contribution of t R and We have 

In order to calculate the push-forward of the above under pi3, we need to know the image of Q[i, j]n x = y and Q [j, i]n x = y under pi3. It will be studied in the following lemma. 

(1) Suppose Supp Jz does not contain x. Then we can decompose Ji as 

This dimension is less than the expected dimension. So we have Pi3 t (i ) = 0. Prom 

SuppCJTa/Js) = for some xeX Then we have an isomorphism similar to (8.23)

This means A > 0, which proves the convexity of the functional J. The proof of Theorem 1.2 is completed. 

This means that u is the solution of problem (1.80). The proof of Theorem 1.11 is completed. 

Taking into account the obtained formula for J(, we complete the proof of Theorem 1.12. 

Repeating the proof of Theorem 1.19 for this case, one deduces that equation (1.119) has a unique solution gV which satisfies... 

It remains to establish the assertion used in the proof of Theorem 2.22. 

As it turns out, the solution of (3.48) is infinitely differentiable provided that f,gG C°°, the crack opening is equal to zero and a contact between plates is absent in the vicinity of the considered point. We prove this assertion in the neighbourhood of a point x, G F n The case x F n F, is simpler (see Remark after the proof of Theorem 3.7). 

We omit a proof of this statement since it is simpler as compared to the proof of Theorem 3.6. 

Now we have to justify an auxiliary statement which has been used in the proof of Theorem 3.8. Let us recall that L, is a segment of the axis x. 

Remark. The specific choice of bijki as the inverse of the Uijki for the elliptic regularization appears to be natural, since in the case of pure elastic (with K = [I/ (R)] , respectively p a) = 0), the boundary condition (5.16) reduces to (5.9). However, the proof of Theorem 5.1 works with any other choice of bijki as long as requirements of symmetry, boundedness and coercivity are met. 

Proof. The general scheme of reasoning coincides with that used in the proof of Theorem 5.3 and our attention now focuses on details related to the nonsmoothness of the boundary. 

Lipschitz boundaries as in the proof of Theorem 5.5. Then, by Lemma 5.1... 

Theorem 4-10 states in effect that Pe cannot be lower bounded in terms of (RT — CT)Tt alone, mid therefore, some source parameter other than the rate is necessary in any lower bound to Pe. Theorem 4-9 is more important than 4-10, but the proof of Theorem 4-10 is simpler and more entertaining so it will be proven first. 

Proof of Theorem 4-10. Choose Tt arbitrarily, and choose two arbitrary numbers, jR0 0, 1 > e > 0. We will construct a source fipr which the rate RT is greater than R0 and a coding and decoding scheme such that Pe e. Let i, 2,- , be the letters in the source alphabet, where if is to be determined later Let... 

Proof of Theorem 4-9. The proof of Theorem 4-9 is somewhat lengthy, but the intuitive idea behind it is simple. We will first show that the equivocation per digit between source and output is at least (BT — CT)Tt. This average uncertainty about the input given the output can be broken into two terms first the uncertainty about whether an error was made and second the uncertainty about the source digit when errors are made. These are the terms on the right side of Eq. (4-66). 

To complete the proof of Theorem 4-11, it is still necessary to show that a code exists that satisfies Eq. (4-91) for every code word. To do this, we show that a code satisfying Eq. (4-91) can be constructed from a code with twice as many code words satisfying Eq. (4-89). Let M and B be the number of code words and rate for the desired code, and let M = 2 if, and R = (In M )/N = jR + (In 2)/2V. We have shown that a code exists of rate B for which, under the circumstances of Theorem 4-11,... 

By the initial hypothesis, P(Po) > 0. Arguing as in the proof of Theorem 3 we arrive at (18). An analog of the remark to Theorem 3 is still valid for that case. 

More specifically, the basic notions of a Turing Machine, of computable functions and of undecidable properties are needed for Chapter VI (Decision Problems) the definitions of recursive, primitive recursive and partial recursive functions are helpful for Section F of Chapter IV and two of the proofs in Chapter VI. The basic facts regarding regular sets, context-free languages and pushdown store automata are helpful in Chapter VIII (Monadic Recursion Schemes) and in the proof of Theorem 3.14. For Chapter V (Correctness and Program Verification) it is useful to know the basic notation and ideas of the first order predicate calculus a highly abbreviated version of this material appears as Appendix A. 

The translation of a recursion augmented program scheme into a recursion scheme Is an elaboration of the construction in the proof of Theorem 7.5. 

C. Proof of Theorem 1 Consider equation (4) written in the form... 

Proof Let S be either a two dimensional abelian variety or a geometrically ruled surface over an elliptic curve over C. Let S be a good reduction of S modulo q, where gcd(q, n) = 1 such that the assumptions of lemma 2.4.7 hold. Then A 5n iis a good reduction of KSn- modulo q. (3) now follows by lemma 2.4.10 and remark 1.2.2. (1) and (2) follow from this by the formula of Macdonald for p(S n z) (see the proof of theorem 2.3.10). ... 

We still have to show that R, ...,R30 generate all relations. For this we have to show that by using them we can express any monomial in B,A,h,p,a,d,fi as an A (X)-linear combination of the elements of the basis from proposition 4.4.4. To show this we use arguments similar to those in the end part of the proof of theorem 4.3.11. In the current case the arguments are however considerably more complicated and make use of the precise form of Ri,..., R3o- We refer to the proof of Satz 4.4.7 in [Gottsche (6)] for the details. ... 

Thus, according to the criterion of Theorem 2, Subsection B, Y, Y belong to different IR s. This completes the proof of Theorem 1, stated above. By means of Theorem 1, we obtain a one-one correspondence (via the Young operators) between diagrams y and IR s 71 y T. We will sometimes refer to a representation and its diagram interchangeably. 

Our approach relies on the description in Theorem 2.1, rather than one given in Theorem 1.14. However, we do not need the proof of Theorem 2.1. Hence the reader who skips Chapter 2 should read the statement of Theorem 2.1 and 2.2. 

We shall give the proof of Theorem 3.30 following [38]. Another proof can be found in...
