... paper of I.Z. Ruzsa and the author [9]. In the present context things look rather different however and, in the absence of anything which might be called a “grain”, we think the terminology of [9] ... we need Theorem 2.1, the restriction theorem for primes. The idea of constructing a 1 , and the technique for constructing it, has its origins in the notions of granularization as...

However, those kinds of considerations can have a major impact on selecting ... stability of nuclear force interactions during a crisis. Indeed, alerts have pluses and minuses. 15 Dealerting focuses only on the minuses, and specific schemes may not have the intend...

In each of these ... of Theorem 3.1. We assume the theorem is false, and we get a sequence of flows M i in U i and points X i ∈ M i such that Θ(M i , X, r) ≤ 1 + ε for all X ∈ M...

After applying the unique embedding of O into Z p which sends α p to a p-adic unit, and rescaling f appropriately, one obtains a form in S 2 (T /Γ) satisfying the conclusion ... embeds in B. Since B is definite of discriminant N − , the algebra K is an imaginary quadratic field in which all prime divisors of N − are inert. Let O K denote the ring of int...
