This booklet constitutes completely revised chosen papers of the fifth foreign convention on Numerical research and Its purposes, NAA 2012, held in Lozenetz, Bulgaria, in June 2012. The sixty five revised papers awarded have been conscientiously reviewed and chosen from a number of submissions. The papers hide a huge quarter of themes of curiosity comparable to numerical approximation and computational geometry; numerical linear algebra and numerical answer of transcendental equation; numerical tools for differential equations; numerical stochastics, numerical modeling; and excessive functionality clinical computing.

See [13]) For α > 0, α = n + 1/2, n ∈ N, the spaces H˙ + (a, b), α α α ˙ ˙ ˙ H− (a, b), Hc (a, b) and H (a, b) are equal and their seminorms as well as norms are equivalent. S. G. Vulkov, and A. Deli´c For the functions of two variables, x and t, defined in the rectangle Q = (0, 1) × (0, T ), we introduce anisotropic Sobolev spaces H α,β (Q), α, β ≥ 0, in the usual manner [14]: H α,β (Q) = L2 ((0, T ), H α (0, 1)) ∩ H β ((0, T ), L2 (0, 1)) . Analogously we define α,β β H± (Q) = L2 ((0, T ), H α (0, 1)) ∩ H± ((0, T ), L2 (0, 1)) .

Li, V. Nistor, and Y. Qiao Step 5. We finally reduce to the case of a half-space or a full space using a partition of unity as in the classical case, as follows. We choose a smooth partition of unity (φj ) on Ω consisting of functions with small supports. The supports should be small enough so that if the support of φj intersects the boundary of Ω or the interface Γ , then the boundary or the interface can be straightened in a small neighborhood of the support of φj . We arrange that the resulting operators are positive and we complete the proof as in [13].
