Abstract
In this paper, we study the Euler and Euler-Poisson equations in Rⁿ, with the multiple γ-law for pressure function: where all γi+1 > γi ≥ 1, are the constants. Analytical line solutions are constructed for the systems. Our novel discovery is the traveling wave solutions for handling the systems with a mixed pressure function and our solutions can be extended to systems with generalized multiple damping and pressure functions. Our solutions also provide concrete examples for testing the validation and stabilities of the systems' numerical methods. Copyright
