Singularities of the Projections of Surfaces in 4
We study the singularities of maps of surfaces from a knot theoretic point of view. We prove that cusps can be canceled on the planar projections of knotted surfaces. For orientable knotted surfaces, we prove that both cusps and branch points can be canceled. We deene and study colors and signs of branch and triple points on knotted surface projections.
متن کاملMinimal Triple Point Numbers of Some Non-orientable Surface-links
An embedded surface in R is projected into R with the double point set which includes a finite number of triple points. We consider the minimal number of such triple points among all projections of embedded surfaces which are ambient isotopic to a given surface and show that for any non-negative integer N there exists a 2-component non-orientable surface in R whose minimal triple point number i...
متن کاملCompact Non-orientable Surfaces of Genus 6 with Extremal Metric Discs
A compact hyperbolic surface of genus g is said to be extremal if it admits an extremal disc, a disc of the largest radius determined only by g. We discuss how many extremal discs are embedded in non-orientable extremal surfaces of genus 6. This is the final genus in our interest because it is already known for g = 3, 4, 5, or g > 6. We show that non-orientable extremal surfaces of genus 6 admi...
متن کاملA Narasimhan - Seshadri - Donaldson Correspondence Over Non - orientable Surfaces
The correspondence between Yang-Mills connections and stable bundles is generalized from orientable to non-orientable surfaces. The theory of d-holomorphic bundles is constructed arising from this generalization. 1991 MS Classification: 53C07, 58E15, 57S17, 14H60.
متن کاملProjections of Immersed Surfaces and Regular Homotopy
This thesis is based on U. Pinkall’s study of the classification of immersions of compact surfaces into R3 up to regular homotopy. The main idea of the classification is to associate to any immersion f a quadratic form qf on the first homology group of the underlying surface Σ with Z2 coefficients, whose associated bilinear form is the nondegenerate intersection form in H1(Σ,Z2), having the pro...
