Higher Frobenius-schur Indicators for Pivotal Categories
We define higher Frobenius-Schur indicators for objects in linear pivotal monoidal categories. We prove that they are category invariants, and take values in the cyclotomic integers. We also define a family of natural endomorphisms of the identity endofunctor on a k-linear semisimple rigid monoidal category, which we call the Frobenius-Schur endomorphisms. For a k-linear semisimple pivotal mono...
متن کاملTHE PIVOTAL ROLE OF CRANIAL NERVER DECOMPRESSION
Reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. Almost all cases of trigeminal neuralgia (TNG) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (HFS) (nine out o...
متن کاملPivotal and Pivotal-discriminative Consequence Relations
In the present paper, we investigate consequence relations that are both paraconsistent and plausible (but still monotonic). More precisely, we put the focus on pivotal consequence relations, i.e. those relations that can be defined by a pivot (in the style of e.g. D. Makinson). A pivot is a fixed subset of valuations which are considered to be the important ones in the absolute sense. We worke...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولeconomic analysis of the pivotal wheat project
the purpose of this article is to evaluate the pivotal irrigated wheat project by cost-benefit analysis method in order to find the internal rate of return and the ratio of present value of net benefits to costs.to this end, we have estimated the economic surplus created due to shift in wheat supply , as result ofimplementation ofthe project and have calculated the above criteria. we found that...
