Reflections in function space

‏‎interpersonal function of language in subtitling

‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

Reflections on Space and Time

The principles of mechanics are already so solidly established that it would be a great error to continue to doubt their truth. Even though we would not be in condition to prove them through the general principles of metaphysics, the marvelous accord of all the conclusions that one obtains through calculation, with all the motion of bodies on earth both solid and fluid, and even with the motion...

On conformal reflections in compactified phase space

Some results from arguments of research dealt with R. Raczka are exposed and extended. In particular new arguments are brought in favor of the conjecture, formulated with him, that both space-time and momentum may be conformally compactified, building up a compact phase space of automorphism for the conformal group, where conformal reflections determine a convolution between space-time and mome...

Real reflections, commutators and cross-ratios in complex hyperbolic space

We provide a concrete criterion to determine whether or not two given elements of PU(2,1) can be written as products of real reflections, with one reflection in common. As an application, we show that the Picard modular groups PU(2, 1,Od) with d = 1, 2, 3, 7, 11 are generated by real reflections up to index 1, 2, 4 or 8.
