Abstract:We prove existence and uniqueness of solutions to the inhomogeneous wave equation on under the assumption that the inhomogeneous data lies in for and . We also require the Fourier transform of the inhomogeneous data to vanish on an infinite cone where the solution could become singular. Subsequently, we show sharpness of the exponent . This extends work of Michael Goldberg, in which similar Fourier-analytic techniques were used to study the inhomogeneous Helmholtz equation.

具有𝐿^ {𝑝}数据的非均匀波动方程
摘要:我们基于不均匀数据位于for和的假设,证明了不均匀波动方程解的存在性和唯一性。我们还需要对不均匀数据进行傅立叶变换,以使其在无限锥上消失,在无限锥上,解可能变得很奇异。随后,我们展示了指数的清晰度。这扩展了迈克尔·戈德堡的工作,其中使用了类似的傅里叶分析技术来研究非均质的亥姆霍兹方程。
