标题： Plane Symmetric Domain Wall in Lyra Geometry

摘要： 本文在Taub给出的平面对称时空度规下，研究了Lyra几何中的畴壁通解。 分别在均匀位移场和时变位移场$\beta$的情况下，推导出畴壁的能量密度和压力的表达式。 同时证明了Rahaman等人的结果 [IJMPD,{\bf 10}, 735 (2001)] 是我们所得到解的特例。 最后，讨论了测地线方程和试验粒子的加速度。 显示英文摘要

摘要： In this paper general solutions are found for domain walls in Lyra geometry in the plane symmetric spacetime metric given by Taub. Expressions for the energy density and pressure of domain walls are derived in both cases of uniform and time varying displacement field $\beta$. It is also shown that the results obtained by Rahaman et al [IJMPD, {\bf 10}, 735 (2001)] are particular case of our solutions. Finally, the geodesic equations and acceleration of the test particle are discussed.
