二维Dirac-Klein- Gordon系统的无条件适定性适定性

Unconditional well-posedness for the Dirac - Klein - Gordon system in two space dimensions

Hartmut Pecher

摘要:

二维Dirac - Klein - Gordon系统的解在自然解空间C^0([0,T],H^s)x C^0([0,T],H ^{s+ \frac 1/2})中唯一确定,其中Dirac数据为H^s,波动数据为H^{s+1/2} x H^{s-1/2},条件是s > 1/30。这改进了A. Gruenrock和作者,其中唯一性证明了(较小)空间的Bourgain型。对于解空间C^0([0,T],L^2)x C^0([0,T],H^{3/5 +})中L^2中的狄拉克数据和H^{3/5}+} x H^{-2/5+}中的波动数据以及更规则的数据,也证明了局部适定性。

英文摘要:

The solution of the Dirac - Klein - Gordon system in two space dimensions with Dirac data in H^s and wave data in H^{s+1/2} x H^{s-1/2} is uniquely determined in the natural solution space C^0([0,T],H^s) x C^0([0,T],H^{s+\frac1/2}), provided s > 1/30 . This improves the uniqueness part of the global well-posedness result by A. Gruenrock and the author, where uniqueness was proven in (smaller) spaces of Bourgain type. Local well-posedness is also proven for Dirac data in L^2 and wave data in H^{3/5}+} x H^{-2/5+} in the solution space C^0([0,T],L^2) x C^0([0,T],H^{3/5+}) and also for more regular data.
