Journal of High Energy Physics, 2022 Abstract Scattering amplitudes in quantum field theories have intricate analytic properties as functions of the energies and momenta of the scattered particles. In perturbation theory, their singularities are governed by a set of nonlinear polynomial equations, known as Landau equations, for each individual Feynman diagram.

Modeling the boundaries of the working space of a planar three-link manipulator [PDF]
Омский научный вестникA study of the boundaries of the working space of a three-link planar manipulator, specified by analytical equations, is carried out. A new geometric interpretation of these samples is proposed. On its basis, it is established that outer space consists

Second-order linear recurrences with identically distributed residues modulo pᵉ [PDF]
Notes on Number Theory and Discrete MathematicsLet p be an odd prime and let u(a,-1) and u(a',-1) be two Lucas sequences whose discriminants have the same nonzero quadratic character modulo p and whose periods modulo p are equal.

Methodic of pedagogic control of 16-17 years’ age girls’ motor fitness
Pedagogics, Psychology, Medical-Biological Problems of Physical Training and Sports, 2016 Increase of schoolchildren’s motor fitness is connected with organization of pedagogic control at physical culture lessons. It was assumed that the basis for pedagogic control of 16-17 years’ age girls’ motor fitness was discriminant model.

Discriminant Diagnostics [PDF]
Biometrics, 1997 I discuss diagnostic methods for discriminant analysis. The equivalence with linear regression is noted and regression diagnostics are considered. The leverage is a function of the linear discriminant function and the Mahalanobis distance of the observation from the group mean.
