Smooth Beginning of the Universe
Jacek Gruszczak
The breaking down of the equivalence principle, when discussed in the context of Sikorski's differential spaces theory, leads to the definition of the so-called differentially sing…
Gravitational Conical Bremsstrahlung and Differential Structures
Jacek Gruszczak
Differential properties of a spin 2 boson field describing propagation of gravitational perturbations on a straight cosmic string's space-time background are studied by me…
Discrete Spectrum of the Deficit Angle and the Differential Structure of a Cosmic String
Jacek Gruszczak
Differential properties of Klein-Gordon and electromagnetic fields on the space-time of a straight cosmic string are studied with the help of methods of the differential space theo…
Differential Structure of Space-Time and Physical Fields
Jacek Gruszczak
A physical interpretation of axioms of the differential structure of space-time is presented. Consequences of such interpretation for cosmic string's space-time with a scalar field…
