Complex Methods for Lie Symmetry Analysis,icity. Making it explicit necessitates the incorporation of the Cauchy–Riemann equations into the original system of equations, which modifies the symmetries of the system. This point was followed up by us, and some of our students, in a series of papers (and theses). It was found that complex metho

,Group Analysis of the Guéant and Pu Model of Option Pricing and Hedging,osts functions. The group classification of the model with a nonlinear execution costs functions is obtained. Symmetries of concrete models are used for invariant solutions and invariant submodels search. The model with the linear execution costs function is reduced to the heat equation. Known resul

On Involutive Systems of Partial Differential Equations,affian systems with fixed independent variables which introduced in this chapter. The system is involutive if and only if the formal extended of the system coincides with the usual extended. This criterion was proved that the order of nontrivial contact transformations allowed by the involutive syst

Approximate Symmetry in Nonlinear Physics Problems,de it possible to construct solutions to a number of boundary value problems in mathematical physics. The chapter presents a review of numerous examples from plasma dynamics and nonlinear optics and acoustics that demonstrate the potentiality of approximate symmetries in constructing approximate analytical solutions.

V. F. Kovalev biological systems have benefitted from the development and availability of three-dimensional organoid cultures which have transformed our understanding of tissue development, homeostasis and regeneration. Such a system does not exist that effectively models the complexity of limb development. Howe
