M ay 2 00 4 UNIVERSAL ABSOLUTE EXTENSORS IN EXTENSION THEORY
Let L be a countable and locally finite CW complex. Suppose that the class of all metrizable compacta of extension dimension ≤ [L] contains a universal element which is an absolute extensor in dimension [L]. Our main result shows that L is quasifinite.
متن کاملUniversal Central Extension of Current Superalgebras
Representation as well as central extension are two of the most important concepts in the theory of Lie (super)algebras. Apart from the interest of mathematicians, the attention of physicist are also drawn to these two subjects because of the significant amount of their applications in Physics. In fact for physicists, the study of projective representations of Lie (super)algebras are very impo...
متن کاملA non-monotonic extension of universal moral grammar theory
We extend universal moral grammar theory (UMGT) with nonmonotonic logic. Our experiment shows that such revision is necessary as it allows to account for the effects of alleviations and aggravations in moral reasoning. Our new theory updates UMGT from classical to non-monotonic logic, which reflects the incompleteness of information and uncertainty in actual human reasoning. In addition, it pro...
متن کاملAbsolute Retracts in Group Theory
The subgroup R of the group G has been termed a retract of the group G whenever there exists an idempotent endomorphism of G which maps G upon R. This definition is in strict analogy to the topological concept of retract. Thus one may be tempted to define absolute retracts in like similarity to topological usage. However, we shall prove in the course of the present note that the identity is the...
متن کاملExtensors in Geometric Algebra
This paper, the third in a series of three introduces the basics of the theory of extensors that are need for the a theory of multvector and extensor fields in arbitrary manifolds, developed in a following series of five papers. Key notions such as the extension and generalization operators of a given linear operator (a (1, 1)-extensor) acting on a real vector space V are introduced and studied...
