Abstract:
In addition to the model of polar ionosphere in terms of ordinary differential equation with random coefficients we construct and investigate two more models: described in terms of a stochastic differential equation in Ito form and in terms of stochastic equation with current velocities (symmetric Nelson's mean derivatives). The existence of solution theorems for those equations are proved.
Keywords:models of polar ionosphere, mean derivatives, current velocities, stochastic equations in Ito form.
