Typical property of one class of combinatory objects and estimation from above corresponding combinatory numbers
We investigate properties of families F of subsets of a finite set in a situation where subsets are incomparable by the binary inclusion relation and a) for any A / ∈ F , there is such set A ′ ∈ F that either A ⊂ A ′ or A ′ ⊂ A; b) for any A ∈ F , | A |∈ {k, k + 1}. For these families we introduce one parametre and we show that for almost all families F the value of this parametre is n−1 k. We ...
متن کاملConcern about one drug or entire class of drugs.
Nonsteroidal antiinfl ammatory drugs (NSAIDs) are the most widely used class of therapeutic agents for the treatment of a variety of acute and chronic rheumatic conditions to provide analgesia and supress infl ammation. Most treatment is short-term management for the relief of signs and symptoms in osteoarthritis, but NSAIDs are widely used too in the long-term treatment of patients with rheuma...
متن کاملAbout one class polynomial problems with not polynomial certificates
About one class polynomial problems with not polynomial certificates Kochkarev B.S. Abstract. We build a class of polynomial problems with not polynomial certificates. The parameter concerning which are defined efficiency of corresponding algorithms is the number n of elements of the set has used at construction of combinatory objects (families of subsets) with necessary properties. Let Σ = {0,...
متن کاملFinite Quantum Fluctuations About Static Field Configurations
We develop an unambiguous and practical method to calculate one-loop quantum corrections to the energies of classical time-independent field configurations in renormalizable field theories. We show that the standard pertur-bative renormalization procedure suffices here as well. We apply our method to a simplified model where a charged scalar couples to a neutral " Higgs " field, and compare our...
متن کاملOn Electro-kinetic Fluids: One Dimensional Configurations
Electro-kinetic fluids can be modeled by hydrodynamic systems describing the coupling between fluids and electric charges. The system consists of a momentum equation together with transport equations of charges. In the dynamics, the special coupling between the Lorentz force in the velocity equation and the material transport in the charge equation gives an energy dissipation law. In stationary...
