Complex model, say C3, of “para-space” as alternative to the real M4 Minkowski space-time for both relativistic and classical mechanics was shortly introduced as reference to our previous works on that subject. The actual aim, however, is an additional analysis of the physical and para-physical phenomena’ behavior as we formally transport observable mechanical phenomena [motion] to non-real interior of the complex domain. As it turns out, such procedure, when properly set, corresponds to transition from relativistic to more classic (or, possibly, just classic) kind of the motion. This procedure, we call the “Newtonization of relativistic physical quantities and phenomena”, first of all, includes the mechanical motion’s characteristics in the C3. The algebraic structure of vector spaces was imposed and analyzed on both: the set of all relativistic velocities and on the set of the corresponding to them “Galilean” velocities. The key point of the analysis is realization that, as a matter of fact, the relativistic theory and the classical are equivalent at least as for the kinematics. This conclusion follows the fact that the two defined structures of topological vector spaces i.e., the structure imposed on sets of all relativistic velocities and the structure on set of all “Galilean” velocities, are both diffeomorphic in their topological parts and are isomorphic as the vector spaces. As for the relativistic theory, the two approaches: the hyperbolic (“classical” SR) with its four-vector formalism and Euclidean, where SR is modeled by the complex para-space C3, were analyzed and compared. 展开更多

The purpose of this article is to define and characterize the general function space F(p, q, s) on Ω. Characterizing functions in the F(p, q, s) space is a work of considerable interest nowadays. In this article, the authors give several equivalent descriptions of the functions in the F(p, q, s) space on Ω in terms of fractional differential operators. At the same time, the authors give the relationship between F(p, q, s) space and Bloch type space on Ω too. 展开更多

Dynamic Equivalence and Skopos Theory are two important translation theories in the fields of translation, which many scholars spare no efforts to research on. This short essay intends to compare and complement between Nida's Dynamic Equivalence and Skopos theory after briefly reviewing these two translation theories. It is aimed for helping readers improve their translation skills via stimulating them to consider translation issues from different angles, such as the nature of translation, the target of translation, translation market, cultural constrains, translation process, translation effects, and etc. And this essay focuses on Nida's Dynamic Equivalence and Skopos theory, a part of functional theories via comparing and harmonizing these two translation theories. 展开更多
