摘要:

AbstractIn this article we shortly present the basic equations of our 5–dimensional Projective Unified Field Theory and their physical interpretation. Our main intention is to confront this theory with physical experience. For this reason we treat the Einstein effects (including the exact solutions for a central body) in detail. Further we once more discuss the first order effects on the quasi–Newtonian level with respect to the equivalence princi

摘要:

AbstractIn order to confront the Projective Unified Field Theory with physical experience it is appropriate to apply this theory also to astrophysical objects, for mathematical reasons in particular to a static spherically symmetric matter distribution as a rough model for a star (e.g. neutron star or another exotic compact object). The problem mentioned is treated here as far as possible analytically in order to prepare the basis for the numerical approach.

摘要:

AbstractIn textbooks the full Schwarzschild problem is usually presented in Schwarzschild coordinates. In the Projective Unified Field Theory (PUFT) these coordinates lead to specific difficulties, whereas isotropic coordinates have the advantage to give explicit results for the exterior solution. Up to now the interior solution in PUFT has had to be treated numerically. For such an approach it is useful to know the interior and exterior solution (including matching at the surface of the sphere) of the Schwarzschild problem in isotropic coordinates in the Einstein theory which can be considered a special case of PUFT.

摘要:

AbstractThe temporal variations of the occurrence of the (M–X) LDE flares (with the SXR duration exceeding 2 hours) throughout the 20th and the 21st cycles are considered. The characteristics of the 20th cycle: the maximum value of the observed yearly number of LDE flares was in the 1970 (with the total 225 LDE flares observed). The increased LDE flare activities were observed in the years 1972 and 1974 (see Tab. 1). The characteristics of the 21st cycle: the large occurrence of the (M–X) LDE flares was observed form 1979 to 1982. The yearly numbers of the (M–X) LDE flares in 1980–168, 1981–151 and 1982–135 are comparable. The fast decrease of the whole flare activity begun at 1983. The percentual representation of the (M–X) LDE flares in the occurrence rate of all Hα flares fluctuate
