A Characterization of the Finite Multiplicity of a Cr Mapping

چکیده
In this paper, we give a characterization of the finite multiplicity of a CR mapping between real analytic hypersurfaces. The finite multiplicity of a CR mapping was defined algebraically by Baouendi and Rothschild in [BR1] (see the definition below). We will prove that under certain conditions on hypersurfaces the finite multiplicity of a CR mapping is equivalent to that the preimage of the map is finite. More precisely,

On Fixed Point Results for Hemicontractive-type Multi-valued Mapping, Finite Families of Split Equilibrium and Variational Inequality Problems
In this article, we introduced an iterative scheme for finding a common element of the set of fixed points of a multi-valued hemicontractive-type mapping, the set of common solutions of a finite family of split equilibrium problems and the set of common solutions of a finite family of variational inequality problems in real Hilbert spaces. Moreover, the sequence generated by the proposed algori...
متن کاملA Study of the Tribological Properties of Sputter-deposited MoSX/Cr Coatings
In this investigation, MoSx/Cr coatings were deposited by direct-current magnetron sputter onto Ck45 (AISI 1045) plain carbon steel substrates. The MoSx/Cr ratio in the coatings was controlled by sputtering the composite targets. The chemical characterization was performed using EDX (energy dispersive X-ray analysis); the structural characterization was accomplished by X-ray diffraction (XRD) s...
متن کاملThe effect of increasing the multiplicity of flow fields contact surface on the performance of PEM fuel cell
In this paper, three innovative 3-D geometries for flow fields of cathode and anode have been developed to investigate the comparative impact of increasing the multiplicity of the involved anode-cathode channel surface contact on the efficiency of electrochemical reaction via the same membrane electrode assembly (MEA) active area. In the introduced new models, each anode channel includes two, t...
متن کاملGorenstein Injective Dimensions and Cohen-Macaulayness
Let (R,m) be a commutative noetherian local ring. In this paper we investigate the existence of a finitely generated R-module of finite Gorenstein dimension when R is Cohen-Macaulay. We study the Gorenstein injective dimension of local cohomology of complexes and next we show that if R is a non-Artinian Cohen-Macaulay ring, which does not have the minimal multiplicity, then R has a finite gener...
متن کاملCharacterization of finite $p$-groups by the order of their Schur multipliers ($t(G)=7$)
Let $G$ be a finite $p$-group of order $p^n$ and $|{mathcal M}(G)|=p^{frac{1}{2}n(n-1)-t(G)}$, where ${mathcal M}(G)$ is the Schur multiplier of $G$ and $t(G)$ is a nonnegative integer. The classification of such groups $G$ is already known for $t(G)leq 6$. This paper extends the classification to $t(G)=7$.
