DISENTANGLEMENTS OF MAPS FROM 2n-SPACE TO 3n-SPACE
نویسنده
چکیده
The first disentanglement of a multigerm f : (ރ 2n , S) → (ރ 3n , 0) is shown to be homotopically equivalent to a wedge of (n+1)-spheres and 2-spheres. For corank-1 monogerms in the same dimensions, the second disentanglement is shown to be homotopically equivalent to a wedge of n-spheres and circles. Good real perturbations of such maps are investigated and it is shown for multigerms in the case n = 1 with a good real perturbation that the real and complex disentanglements are homotopically equivalent.

Let M^2n be a hoph hypersurfaces with parallel ricci operator and tangent to structure vector field in Sasakian space form. First, we show that structures and properties of hypersurfaces and hoph hypersurfaces in Sasakian space form. Then we study the structure of hypersurfaces and hoph hypersurfaces with a parallel ricci tensor structure and show that there are two cases. In the first case, th...
متن کاملOn the pointfree counterpart of the local definition of classical continuous maps
The familiar classical result that a continuous map from a space $X$ to a space $Y$ can be defined by giving continuous maps $varphi_U: U to Y$ on each member $U$ of an open cover ${mathfrak C}$ of $X$ such that $varphi_Umid U cap V = varphi_V mid U cap V$ for all $U,V in {mathfrak C}$ was recently shown to have an exact analogue in pointfree topology, and the same was done for the familiar cla...
متن کاملTangent Bundle of the Hypersurfaces in a Euclidean Space
Let $M$ be an orientable hypersurface in the Euclidean space $R^{2n}$ with induced metric $g$ and $TM$ be its tangent bundle. It is known that the tangent bundle $TM$ has induced metric $overline{g}$ as submanifold of the Euclidean space $R^{4n}$ which is not a natural metric in the sense that the submersion $pi :(TM,overline{g})rightarrow (M,g)$ is not the Riemannian submersion. In this paper...
متن کاملA criterion for a proper rational map to be equivalent to a proper polynomial map
Let B be the unit ball in the complex space C. Write Rat(B,B) for the space of proper rational holomorphic maps from B into B and Poly(B,B ) for the set of proper polynomial holomorphic maps from B into B . We say that F and G ∈ Rat(B,B) are equivalent if there are automorphisms σ ∈ Aut(B) and τ ∈ Aut(B ) such that F = τ ◦G◦σ. Proper rational holomorphic maps from B into B with N ≤ 2n− 2 are eq...
متن کاملCharacterizing imageability in Gajar houses of Tabriz
Aims: From Lufor’s perspective, space is constructed based on spatial operation, recreation and the space in which recreation takes place. This approach is a descriptive view of the relationship between space from a materialistic point of view and its dominant ideas with its dwellers. In this perspective, humans integrate distinct and indistinct data of space and create map-like mental images f...
