https://doi.org/10.1007/978-3-531-19592-6e motion of a finite mass of an ideal self-gravitating gas limited by a free boundary. A theorem of existence and uniqueness of the solution of the problem of motion of a rarefied gas in the space of infinitely differentiable functions is formulated and proved. The solution is constructed as a serie

Connections between ART of various orders are established, and corresponding differential equations and uniqueness theorems are obtained. We define the angular moments of ART of order ., represe

The first method consists in a generalization of the Godunov–Powell terms, which means adding suitable multiples of the involution constraints

https://doi.org/10.1007/978-3-531-19619-0such systems suffer from a few major deficiencies such as nonuniform coverage of space, loss of accuracy close to the pole, and severe limitation on time stepping. Additionally, it becomes increasingly important to have higher orders of accuracy in order to reduce the dissipation and dispersion. In

https://doi.org/10.1007/978-3-531-19469-1The transport equation in an inhomogeneous medium is considered. The coefficients of this equation undergo a gap at the boundaries of inhomogeneities. To search for discontinuity surfaces of these coefficients, it is proposed to consider a function that will be unbounded on them.
