Geometrical theory of shear-wave splitting: corrections to ray theory for interference in isotropic/anisotropic transitions
TL;DR: In this article, it was shown that if the elasticity and its first two derivatives are continuous at the isotropy/anisotropy border, then zeroth-order ray theory may still be used to continue the incident wave into the anisotropic region.

Local Moduli of Semisimple Frobenius Coalescent Structures
TL;DR: In this article, the authors extend the analytic theory of Frobenius manifolds to semisimple points with coalescing eigenvalues of the operator of multiplication by the Euler vector field.

Non-integrability of first order resonances in Hamiltonian systems in three degrees of freedom
TL;DR: In this article, the normal forms of the Hamiltonian 1:2:ω resonances to degree three for ω = 1, 3, 4 are studied for integrability.

Computing super-irreducible forms of systems of linear differential equations via moser-reduction: a new approach
TL;DR: This paper gives a new algorithm for computing, given an arbitrary linear differential system with formal power series coefficients as input, an equivalent system which is super-irreducible.

Ilya Kossovskiy,Rasul Shafikov +1 more
TL;DR: In this article, the analytic theory of differential equations is used to construct real-analytic CR-submanifolds in complex space, in any positive CR-dimension and CR-codimension.
