Now, we study the integrability, in Galoisian sense, of this equation through Kovacic Algorithm. We consider the differential Galois theory in the context of second order linear eqaution equations.

In this case the ODEs are in the complex domain and differentiation is with respect to a complex variable. Enter the email address you signed up with and we’ll email you a reset link. Although there are a plenty of papers concerning to explicit solutions and harmonic oscilla- tor see [12]we recall that differential Galois theory can provide the Liou- villian solutions of characteristic equations without previous knowledge of such equations.

## Histoire des équations

As in [32], we obtain three conditions for n to get virtual solv- ability of the differential Galois group. Further, the following asymptotics hold: Consider now the following forms associated to any second order differential equation ode and Riccati equation: Dofferentielle non-linear Riccati equation can always be reduced to a second order linear ordinary differential equation ODE: This doesn’t mean that anyone who uses your computer can access your account information as we separate association what the cookie provides from authentication.

The fact that in quan- tum electrodynamics the electromagnetic field can be represented as a set of forced harmonic oscillators makes quadratic Hamiltonians of special interest [7, 8, 11, 14, 35, 39].

### Riccati equation – Wikipedia

In this way, we can give a Galoisian for- mulation for this kind of integrability. The problem with Maple is that the answers can have complicated expressions that should be trans- formed into more suitable and readable expressions.

Moreover, diffrrentielle applications to mathematical physics can be found in [1, 3, 27, 28, 32]. Primary 81Q05; Secondary 12H From Wikipedia, the free encyclopedia. Ko- vacic in [17] and Hamiltonian Algebrization developed by the first author in [1, 3]. The Hamiltonian 2 had also been considered by Angelow and Trifonov [4, 5] in order to describe the light propagation in a nonlinear anisotropic waveguide.
