Small Fluctuations in $\lambda {\varphi }^{n+1}$ Theory in a Finite Domain: An Hirota's Method Approach

M. C. Gama, J. A. Espichán Carrillo, A. Maia

We present a method to calculate small stationary fluctuations around static solutions describing bound states in a $(1+1)$-dimensional $\lambda {\varphi }^{n+1}$ theory in a finite domain. We als…
