In present, a lot of disciplines, per se physical ones (the probability theory and the rational mechanics, in particular) are presented as the abstract mathematical theories. Therefore the sixth D. Gilbert's problem connected with axiomatization of physical disciplines has not solved so far. For physical disciplines, for which axiomatic mathematic theories are created the solution of the problem can be provided by the additional physical hypotheses (the adequacy axioms) that fix the presence and the particularities of the base of physical phenomena. Demands for the physical hypotheses are formulated. Fig.: 1. Refs.: 11 titles.

The ways of solving Ax=b systems for special parallel type processor on the base of processing elements (PE) with a scalar multiplier (SM) within each PE are suggested. Matrix factorization of p*p size is suggested to perform by the methods allowing to reduce the number of divisions operations on the direct route of exceptions in n-times. On the return route of calculation of indeterminate it is proposed to exclude a division, performing in PE on SM only the operations of multiplication and totalling. Refs.: 8 titles.
