Asymptotic Structure of Cosmological Burgers Flows in One and Two Space Dimensions: A Numerical Study

We study the cosmological Burgers model, as we call it, which is a nonlinear hyperbolic balance law (in one and two spatial variables) posed on an expanding or contracting background. design finite volume scheme that fourth-order in time second-order space, allows us to compute weak solutions containing shock waves. Our main contribution of asymptotic structure variable approaches infinity case) zero case). discover saddle competition taking place involves, hand, geometrical effects nature and, other interactions between
