... In this paper we shall present a direct bicubic spline collocation method for solving numerically the Dirichlet problem for the Poisson’s equations (1) .Such methods have been developed in many papers in the last ... Lihat dokumen lengkap

... Let a, b, c be integers. The Frobenius problem is to determine the greatest integer n which cannot be represented as a positive linear combination of a, b, c; this integer will henceforth be denoted by f(a, b, c). Of ... Lihat dokumen lengkap

... where D is a smooth domain, div f (x) is a divergence of the vector field f (x), n(x) denotes the exterior normal vector at x ∈ ∂ D, and σ D (d x) denotes the surface measure on ∂ D. In the case that f is a scalar field ... Lihat dokumen lengkap

... Remark. It is an important feature of the proof (similar to the argument in [6]) that the representation (2.5) of the off-diagonal elements is determined without reference to the function g that defines the diagonal ... Lihat dokumen lengkap

... the process ˜ Z stopped at its first hitting time of [0, M /(1 − c)] is a positive super-martingale which converges almost surely. Since no state in ( M/(1 − c), ∞ ) is absorbent for ˜ Z, we deduce that ˜ Z ... Lihat dokumen lengkap

... For the coupled branching process with p > 0 there is a dichotomy too, but it is controlled by a subtle interplay of a( · , · ), b and p: extinction holds when a( · , · ) is recurrent, but also when a( · , · ) is ... Lihat dokumen lengkap

... In the manifold case the zero-set N (viewed as an embedded manifold in C 2 ) has a natural Rie- mannian structure and hence there is a canonical Brownian motion induced by the Kähler metric, see for instance [IW81]. In ... Lihat dokumen lengkap

... ∞ 1 is a sequence in Q(p, p, r, ε), p, r ∈ [ε, 1 − 2ε] and µ 0 = ν ≡ 1/(N + 1), µ n = ν K 0,n , then the j-th singular value σ j (K i , µ i−1 ) is bounded ... Lihat dokumen lengkap

... Note that the infimum in the definition of T n+1 is always taken on a finite set. Moreover, Assumption (5) ensures that if this infimum is reached by several triplets (i, y, z), all these triplets have the same ... Lihat dokumen lengkap
