Topological Aspects

چکیده
Parasupersymmetric quantum mechanics is exploited to introduce a topological invariant associated with a pair of parameter dependent Fredholm (respectively elliptic diierential) operators satisfying two compatibility conditions. An explicit algebraic expression for this topological invariant is provided. The latter identiies the parasupersymmetric topological invariant with the sum of the analytic (Atiyah-Singer) indices of the corresponding operators.

Algebraic and topological aspects of quasi-prime ideals
In this paper, we define the new notion of quasi-prime ideal which generalizes at once both prime ideal and primary ideal notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which admits the Zariski topology as a subspace topology. The basic properties of the quasi-prime spectrum are studied and several interesting results are obtained. Specially, it is pro...
متن کاملAn introduction to Topological Data Analysis: fundamental and practical aspects for data scientists
Topological Data Analysis (TDA) is a recent and fast growing field providing a set of new topological and geometric tools to infer relevant features for possibly complex data. This paper is a brief introduction, through a few selected topics, to basic fundamental and practical aspects of TDA for non experts.

The aspect graph (AG) has been proposed as a viewer-centered tool for object recognition. Although the aspects could be used for recognition from one image,the full information stored in the AG (aspects and visual events) suggests a multiple views, possibly active, approach. The topological nature of the AG also suggests a topological match of images of the unknown object and stored aspects. In...
متن کاملTopological Aspects in Genetic Algorithms
We investigate topological aspects in Genetic Algorithms (GAs). Two dimensional combinatorial optimization problems, cell placement problems, are concerned. We construct topological recombination and uniform recombination based on exchange operations, and compare their performance. Simulation results show that the contributions of these recombinations are qualitatively di erent.
متن کاملTopological recognition of polyhedral objects from multiple views
The aspect graph (AG) has been proposed as a viewer-centered tool for object recognition. Although the aspects could be used for recognition from one image, the full information stored in the AG (aspects and visual events) suggests a multiple views, possibly active, approach. The topological nature of the AG also suggests a topological match of images of the unknown object and stored aspects. I...
