... second term on the right-hand side of the analogue of (2.93). 4. Proof of Theorem 3 In Sections 4–6 we prove Theorems 3–5. The proof follows the same line of reasoning as in [3, §5], but there ... 1.(2.93) Substitution into (2.82) yields the claim in (2.80). This completes the proof of Lemma 6. This completes the proof of Proposition 4 and hence of Theorem 1. 3....

... for the size of the neighbourhood V of the singular set on noncontracted components is the diameter of ϕ(V )inM; on contracted components one may take the smallest ε with V contained in the ε-thin ... pull-back of the relative tangent bundle. The ¯ ∂ J -equation giving J-holomorphic deformations of σ acts on the latter bundle. On the other hand, the mid...

... component of type (i), then the intersection in codimension one of any two distinct components can only be a line. If there is no component of type (i), then the intersection in codimension one of ... X 2 meeting along a conic. If there are THE K 2 OF DEGENERATIONS OF SURFACES 361 other components, then there is a component X  meeting all the rest along a line. Thus, the...

Keep the notation and the assumptions of this theorem. ... decide whether every element of Q(β) ∩(0, 1) has an eventually periodic β-expansion. 5. Proofs of Theorems 1 to 4 We begin by a short proof of Theorem 2. Proof of Theorem...

This leads to the conjecture of Gross-Deligne, which is described precisely in the last section of this paper. The main contribution of...

The PCP theorem ... construction proceeds by transformations on graphs rather than on constraint satisfaction systems. We employ a well-known reduc- tion [FGL + 96] converting the constraint sati...
