The Inviscid Limit of Viscous Burgers at Nondegenerate Shock Formation

نویسندگان

چکیده

We study the vanishing viscosity limit of one-dimensional Burgers equation near nondegenerate shock formation. develop a matched asymptotic expansion that describes small-viscosity solutions to arbitrary order up moment first forms. The inner part this has novel structure based on fractional spacetime Taylor series for inviscid solution. obtain sharp rates in variety norms, including $$L^\infty $$ . Comparable prior results break down vicinity partially fill gap.

Viscous and Inviscid Stability of Multidimensional Planar Shock Fronts

We explore the relation between viscous and inviscid stability of multi-dimensional shock fronts, by studying the Evans function associated with the viscous shock proole. Our main result, generalizing earlier one-dimensional calculations, is that the Evans function reduces in the long-wave limit to the Kreiss{Sakamoto{ Lopatinski determinant obtained by Majda in the inviscid case, multiplied by...

Problem and Inviscid Burgers

Let F (z) = z−H(z) with order o(H(z)) ≥ 1 be a formal map from C to C and G(z) the formal inverse map of F (z). We first study the deformation Ft(z) = z − tH(z) of F (z) and its formal inverse Gt(z) = z + tNt(z). (Note that Gt=1(z) = G(z) when o(H(z)) ≥ 2.) We show that Nt(z) is the unique power series solution of a Cauchy problem of a PDE, from which we derive a recurrent formula for Gt(z). Se...

Shallow Water Equations: Viscous Solutions and Inviscid Limit

We establish the inviscid limit of the viscous shallow water equations to the Saint-Venant system. For the viscous equations, the viscosity terms are more degenerate when the shallow water is close to the bottom, in comparison with the classical NavierStokes equations for barotropic gases; thus the analysis in our earlier work for the classical Navier-Stokes equations does not apply directly, w...

Global well posedness and inviscid limit for the Korteweg-de Vries-Burgers equation

Considering the Cauchy problem for the Korteweg-de Vries-Burgers equation ut + uxxx + ǫ|∂x| u+ (u)x = 0, u(0) = φ, where 0 < ǫ, α ≤ 1 and u is a real-valued function, we show that it is globally well-posed in Hs (s > sα), and uniformly globally well-posed in H s (s > −3/4) for all ǫ ∈ (0, 1). Moreover, we prove that for any T > 0, its solution converges in C([0, T ]; Hs) to that of the KdV equa...

Global well-posedness and inviscid limit for the modified Korteweg-de Vries-Burgers equation

Considering the Cauchy problem for the modified Korteweg-de Vries-Burgers equation ut + uxxx + ǫ|∂x| u = 2(u)x, u(0) = φ, where 0 < ǫ, α ≤ 1 and u is a real-valued function, we show that it is uniformly globally well-posed in Hs (s ≥ 1) for all ǫ ∈ (0, 1]. Moreover, we prove that for any s ≥ 1 and T > 0, its solution converges in C([0, T ]; Hs) to that of the MKdV equation if ǫ tends to 0.
