(3+1)维Signum-Gordon模型的标度不变性和自相似演化

Note on scale invariance and self-similar evolution in (3+1)-dimensional signum-Gordon model

H. Arodz, J. Karkowski, Z. Swierczynski

摘要:

本文给出了几类具有符号形式非线性项的相对论性波动方程的自相似球对称解。它们由尺度不变变量t/r的三次多项式构造而成。一类解描述了初始场消失的过程,另一类解描述了场能量在有限且不断增长的空间区域中的积累。

英文摘要:

Several classes of self-similar, spherically symmetric solutions of relativistic wave equation with nonlinear term of the form sign(ϕ) are presented. They are constructed from cubic polynomials in the scale invariant variable t/r. One class of solutions describes a process of wiping out the initial field, another an accumulation of field energy in a finite and growing region of space.
