Linking and Coincidence Invariants
Given a link map f into a manifold of the form Q = N ×R, when can it be deformed to an “unlinked” position (in some sense, e.g. where its components map to disjoint R-levels)? Using the language of normal bordism theory as well as the path space approach of Hatcher and Quinn we define obstructions ω̃ε(f), ε = + or ε = −, which often answer this question completely and which, in addition, turn ou...
متن کاملNonstabilized Nielsen coincidence invariants and Hopf--Ganea homomorphisms
In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. We extend it to pairs (f1, f2) of maps between manifolds of arbitrary dimensions, using nonstabilized normal bordism theory as our main tool. This leads to estimates of the minimum numbers MCC(f1, f2) (and MC(f1, f2), resp.) of pathcomponents (and of points, resp.) in the coinciden...
متن کاملFinite Type Invariants of Links with a Fixed Linking Matrix
Abstract. In this paper we introduce two theories of finite type invariants for framed links with a fixed linking matrix. We show that these theories are different from, but related to, the theory of Vassiliev invariants of knots and links. We will take special note of the case of zero linking matrix. i.e., zero-framed algebraically split links. We also study the corresponding spaces of “chord ...
متن کاملLinking Perceived Employee Voice and Creativity
Researchers are of the belief that employee voice has favorable effects for both the employee and the organization. However, the effect of employee voice on creativity, and the process through which it influences creativity, has hitherto received little attention. This study aimed at investigating the relationship between perceived employee voice and creativity. Employees of three premier dairy...
متن کاملCompetency-Based Curriculum: Linking Theory and Practice
Background and objective: Most higher education curricula do not provide the competencies graduates need in the occupational fields, resulting in waste of money and lower effectiveness while increasing the number of unemployed graduates. Competency-based education is an innovative educational model that can solve such problems and lead education activists to design competency-based curricula. T...
