Some Peculiarities of Speech Behavior in Formal and Business StyleThe problems of speech behavior and speech stereotypes in 
formal and business style are considered
 A geometric approach to the Lagrangian and Hamiltonian formalism of electrodynamics and Hamiltonian 
formalisms. Hamiltonian 
formalism of field theory has the advantage over the Lagrangian, which
 Inverse problem of the calculus of variations for systems of differential-difference equations of second order of 
differential-difference equations is considered. The relationship between the 
formal potentiality of a linear

 Stability of Periodic Solutions for Hysteresis-Delay Differential Equations. The main object we study is a Poincaré map that is infinite-dimensional due to delay and non-
differentiable Stochastization of one-step processes in the occupations number representation study. We want to get a unified abstract 
formalism for stochastization of one-step processes
 Spin 3/2 Particle in the Presence of Magnetic Field: Tetrad Formalism and Fedorov-Gronskiy Method result we derive the system of 16 first order 
differential equations in the variable r. To resolve
