... The aim of this paper is to establish some theorems on the smoothness of generalized solutions of the problem in domains with conical points on boundary. Let Ω be a bounded domain in R n . Its boundary ... solutions of the first initial b oundary value problem for strongly Schr¨odinger systems in domains with conical p oints on boundary are given. 1. Introduction Boundary value problems for Sc...

... 1+ i  j=2 2 j−2 =2 i−1 . This completes the proof of the lemma. The above lemma yields r(n)=s k (n)≤2 k−1 ≤ 1 2 ·2 log 3 (n) = 1 2 · n α which completes the proof of Theorem 1. 2. Proofoftheorem2 We introduce the following ... Professor Carl Pomerance for suggesting these problems, and also for his counsel as the work progressed. 1. Proofoftheorem1 Lemma 1. r(2 a 3 b m)=r(m) Proof. It is eno...

... g f is not a proper coloring, i.e., that some e j is monochromatic of some color i under g f .Butsomev  ∈ e j must be f(w i,j ), and therefore g f (v  ) = i, a contradiction. This proves that ... has a coloring f from the lists. Since G is a complete k-partite graph, every color v is used on at most one part. Then f produces a k-coloring g f of V as follows: we let g f (v) be equal to the...

... diagram of a 231-avoiding Schr¨oder permutation has to look. Corollary 3.12 The diagram of a Schr¨oder permutation satisfies the conditions of Propo- sition 3.11 if and only if it is of the following ... permutations are known to have a lot of properties which are analogous to properties of 132-avoiding permutations. A look at their diagrams shows why this is so. Given a permutation π ∈S n ,we...

... Woodall [3] gave a detailed proof of the two following propositions: Theorem 1 If a ∈ S ∗ n , then ¯ d(a, a)=Z(n). Theorem 2 In a drawing D of K 2,n on two sets {x, x  } and V n , let the clockwise ... where each two edges have at most one point in common, which is either a common end vertex or a crossing. Clearly a drawing with minimum crossing number must be a good drawing. Let A be one pa...

... there is a nontrivial linear combination of rows of K 2 × n equal to 0. Let τ Γ be the coefficient of the row corresponding to a horizontal tableau Γ in this combination. Then for a column of K 2 × ... each  Γ⊥∆ τ Γ is zero by the assumption above, the sum  Γ⊥∆  τ Γ is also 0, which means that orthogonality to ∆  is a 0-filter. We now continue the proof of Theorem 2.1. Choose a particular ho...
