On Regular Homotopy in Codimension 1

The Annals of Mathematics, 1966
dfx: T(M) x T(N)f (x, is injective. The space Hom (M, N) of maps M N will be endowed with the C'topology p > 3. In particular, if Imm (M, N) is the space of immersions ME N, which will be endowed with the induced topology, any continuous arc A: I-n Imm (M, N) will be called a regular homotopy.

Regular homotopy for immersions of graphs into surfaces

Sbornik: Mathematics, 2016
We study invariants of regular immersions of graphs into surfaces up to regular homotopy. The concept of the winding number is used to introduce a new simple combinatorial invariant of regular homotopy. Bibliography: 20 titles.

Solving viscid Burgers equation by Adomian decomposition Method (ADM), Regular Pertubation Method (RPM) and Homotopy Perturbation Method (HPM)

open access: diamondInternational Journal of Applied Mathematical Research
In this paper the Adomian decomposition Method (ADM), Regular Pertubation Method (RPM) and the Homotopy Perturbation Method (HPM) are used to study Burgers equation. Then we compare the solutions obtained by these three methods.

Regular topological group action yield sections of Core higher homotopy groupoid bundle

open access: diamondProyecciones (Antofagasta)
In this paper, we discuss sections of higher homotopy groupoid bundles those yield by group actions. We study some basic properties related to the left-invariant (G-invariant) of such sections and also present some conditions for such sections to be left-

Regular homotopy classes of immersions of 3-manifolds into 5-space [PDF]

open access: green, 2001
We give geometric formulae which enable us to detect (completely in some cases) the regular homotopy class of an immersion with trivial normal bundle of a closed oriented 3-manifold into 5-space.

Homotopy Regularization for Boosting

2010 IEEE International Conference on Data Mining, 2010
In this paper, we present a homotopy regularization algorithm for boosting. We introduce a regularization term with adaptive weight into the boosting framework and compose a homotopy objective function. Optimization of this objective approximately composes a solution path for the regularized boosting.

Links of singularities up to regular homotopy

The Journal of Singularities, 2013
The abstract link L_d of the complex isolated singularity x^2 + y^2 + z^2 + v^{2d} = 0 is diffeomorphic to S^3 \times S^2. We classify the embedded links of these singularities up to regular homotopies precomposed with diffeomorphisms of S^3 \times S^2 ...

A Homotopy Shape Solution for Thickness-Vibration of Centrally Partially Electroded Regular Polygonal At-Cut Quartz Resonators

Symposium on Piezoelectricity, Acoustic Waves and Device Applications, 2019
In this paper, the homotopy polygonal electrode is applied in the quartz crystal resonator, whose shapes are determined by homotopy transform. For theoretical analysis, the ST two-dimensional scalar differential equation is used and the displacement is ...
