Streszczenie
We are concerned with the global existence and asymptotic behavior of classical solutions to the Cauchy problem for the full compressible Euler equations with damping in $\mathbb R^3$. We prove the global existence of the classical solutions by the delicate energy method under the condition that the initial data are close to the constant equilibrium state in $H^3$-framework. An energy estimate on $\| \nabla u\| _{L^1((0,t);\tilde{B}^{0,{3/2}}_{2,1}(\mathbb R^3))}$ enables us to close the energy estimates for the non-dissipative entropy. Moreover, the optimal time decay rate is also established.
