Ritt - Wu ’ s Decomposition Algorithm ∗
An improved Ritt-Wu’s decomposition (of an algebraic set into the union of irreducible varieties) algorithm is given. The algorithm has been used to prove geometric theorems that Wu’s original method addresses. Unlike Wu’s original approach, nondegenerate conditions are given explicitly at the beginning, not generated during the proof process. A program based on this improved version of the alg...
متن کاملA model for the hillock formation on graphite surfaces by 246 MeV Kr+ ions.
Scanning tunnelling microscopy has been used to study the effect of ion bombardment at different angles of incidence on a graphite surface. The 246 MeV energy of Kr+ ions was selected in the medium energy range, where the electronic and nuclear stopping is nearly balanced. The low dose (1 x 10(12)/cm2) of ions allows the characterization of single features caused by bombardment in perpendicular...
متن کاملBlood Viscosity in Waldenstr # { 246 } m ’ s Macroglobulinemia
Erythrocytes and plasma proteins contribrelated (p < 0.001) with the plasma ute to viscosity of blood. Therefore, blood macroglobulin concentration in g/100 ml. viscosity was measured in 16 persons with The plasma of patients with macroglobumacroglobulinemia with a cone-plate vislinemia is a non-Newtonian fluid, but at a cometer at defined shear rates. In each given shear rate the plasma viscos...
متن کاملThe integral sum number of complete bipartite graphs Kr, s
A graph G=(V; E) is said to be an integral sum graph (sum graph) if its vertices can be given a labeling with distinct integers (positive integers), so that uv ∈ E if and only if u+ v ∈ V . The integral sum number (sum number) of a given graph G, denoted by (G) ( (G)), was de:ned as the smallest number of isolated vertices which when added to G result in an integral sum graph (sum graph). In th...
متن کاملN ov 2 00 4 Ritt ’ s theorem and the Heins map in hyperbolic complex manifolds
Abstract. Let X be a Kobayashi hyperbolic complex manifold, and assume that X does not contain compact complex submanifolds of positive dimension (e.g., X Stein). We shall prove the following generalization of Ritt’s theorem: every holomorphic self-map f :X → X such that f(X) is relatively compact in X has a unique fixed point τ(f) ∈ X , which is attracting. Furthermore, we shall prove that τ(f...
