<正>Real Submanifolds in Complex Spaces Valentin BURCEA Abstract Let(z_(11),...,z_(1N),…,z_(m1),…,z_(mN),w_(11),…,w_(mm))be the coordinates in C~(mN+m~2).In this note we prove the analogue of the Theorem of Moser in the case of the real-analytic submanifold M defined as follows W=ZZ~t+O(3),where W={w_(ij)}_(1≤i,j≤m)and Z={z_(ij)}_(1≤i≤m,1≤j≤N).We prove that M is biholomorphically equivalent to the model W=ZZ~t if and only if is formally equivalent to it.  相似文献

正A Comparison between the Metric Dimension and Zero Forcing Number of Trees and Unicyclic Graphs Linda EROH Cong X.KANG Eunjeong YI Abstract The metric dimension dim(G)of a graph G is the minimum number of vertices such that every vertex of G is uniquely determined by its vector of distances to the chosen vertices.The zero forcing number Z(G)of a graph G is the minimum cardinality of a set S of  相似文献

正Nonlinear Branching Processes with Immigration Pei Sen LI Abstract The nonlinear branching process with immigration is constructed as the pathwise unique solution of a stochastic integral equation driven by Poisson random measures.Some criteria for the regularity,recurrence,ergodicity and strong ergodicity of the process are then established.  相似文献

正Some Specific Unboundedness Property in Smoothness Morrey Spaces.The Non-existence of Growth Envelopes in the Subcritical Case Dorothee D.HAROSKE Susana D.MOURA Abstract We study smoothness spaces of Morrey type on R~n and characterise in detail those situations when such spaces of type A_(p,q)~(s,r)(R~n)or A_(u,p,q)~s(R~n)are not embedded into L_∞(R~n).We can show that in the so-called sub-critical,proper Morrey case their growth envelope function  相似文献
