General Theory of Unary Intensional Connectives

1976
Unary connectives are of special interest as many known intensional operators such as necessity, tense operators, statability operators etc. are unary. We therefore begin with the study of the general properties of one unary connective. Our plan is to study various possible N-logical systems X, with one unary connective and analyse their corresponding ...

The connecting homomorphism for K-theory of generalized free products

Geometriae Dedicata, 2010
In the paper the author considers a category \(\mathcal C\) with cofibrations and two subcategories of weak equivalences, \(v{\mathcal C} \subset w{\mathcal C} .\) Let \({\mathcal C}^{w}\) denote the subcategory with cofibrations of \({\mathcal C}\) which consists of the objects \(A\) of \({\mathcal C}\) such that the map \(* \rightarrow A\) is in \(w{\

Serre Fibering. General Theory of Connection. Corollaries

1997
In his (classical now) Ph.D. thesis Homologie singuliere des espaces fibres. Applications, Ann. of Math. 54 (1951), 425–501, which, at that time, electrified the mathematical world, very young Jean-Pierre Serre (born in 1926) turn the things upside down: He takes the axiom of covering homotopy as the definition of a fiber space. In section 2 of chapter

Transient theory of synchronous generators connected to power systems

Proceedings of the IEE - Part II: Power Engineering, 1951
Practical methods of predetermining the transient performance of synchronous generators have in the past been based more on general considerations than on a strictly logical theory. On the other hand, general equations for the synchronous machine were derived by R. H.

A theory of general relativity by general connections. II

1985
In a previous paper [ibid. 20, 173-187 (1984; Zbl 0569.53010)], the author extended Einstein's theory of gravitation within the limits of the theory of general metric connections \(\Gamma\) (\(\Psi\) (x),G) and got a system of partial differential equations on \(\Gamma\) (\(\Psi\) (x),G): \[ (0.1)\quad \Psi^ 3(R^{\mu \nu}-g^{\mu \nu}S)- (\nabla_ ...

Generalized affine connections applied to a unified field theory

Physical Review D, 1982
The structure of the affine space is generalized by assuming that the change in a vector upon parallel transportation is given by terms containing not only a three-index symbol, but a one-index symbol as well. The relation between the affine connections and the metric tensor is established by the requirement that the length of a vector remains constant
