Four-Quadrant Riemann Problem for a 2×2 System II
Mathematics, 2021 In previous work, we considered a four-quadrant Riemann problem for a 2×2 hyperbolic system in which delta shock appears at the initial discontinuity without assuming that each jump of the initial data projects exactly one plane elementary wave.

The limit Riemann solutions to nonisentropic Chaplygin Euler equations
Open Mathematics, 2020 We mainly consider the limit behaviors of the Riemann solutions to Chaplygin Euler equations for nonisentropic fluids. The formation of delta shock wave and the appearance of vacuum state are found as parameter ε\varepsilon tends to a certain value ...

Limits of Riemann Solutions to the Relativistic Euler Systems for Chaplygin Gas as Pressure Vanishes
Abstract and Applied Analysis, 2013 Vanishing pressure limits of Riemann solutions to relativistic Euler system for Chaplygin gas are identified and analyzed in detail. Unlike the polytropic or barotropic gas case, as the parameter decreases to a critical value, the two-shock solution ...

Limit of Riemann Solutions to the Nonsymmetric System of Keyfitz-Kranzer Type
The Scientific World Journal, 2014 The limit of Riemann solutions to the nonsymmetric system of Keyfitz-Kranzer type with a scaled pressure is considered for both polytropic gas and generalized Chaplygin gas.

Boundary Value Problems, 2018 The Riemann problem for a compressible perfect fluid with a constant external force for the Chaplygin gas is considered. We obtain two kinds of exact solutions. The first one consists of contact discontinuities, while the other one involves a delta shock

Heliyon, 2020 In 1977 Korchinski presented a new type of shock discontinuity in conservation laws. These singular solutions were coined δ-shocks since there is a time dependent Dirac delta involved.

Advances in Mathematical Physics, 2019 We analyze the appearance of delta shock wave and vacuum state in the vanishing pressure limit of Riemann solutions to the non-isentropic generalized Chaplygin gas equations.

Nonlinear low-frequency wave aspect of foreshock density holes [PDF]
Annales Geophysicae, 2008 Recent observations have uncovered short-duration density holes in the Earth's foreshock region. There is evidence that the formation of density holes involves non-linear growth of fluctuations in the magnetic field and plasma density, which results ...

Four-Quadrant Riemann Problem for a 2 × 2 System Involving Delta Shock
Mathematics, 2021 In this paper, a four-quadrant Riemann problem for a 2×2 system of hyperbolic conservation laws is considered in the case of delta shock appearing at the initial discontinuity.
