In this paper, based on a systematic formulation of Lax pairs, we show classical integrability for nonrelativistic strings propagating over stringy Newton-Cartan (NC) geometry. We further construct the corresponding monodromy matrix which leads to an infinite tower of non-local conserved charges over stringy NC background.

牛顿卡坦几何线的松散对

在本文中，基于Lax对一个系统的提法，我们展示经典的非相对论弦传播过积粘性的牛顿-嘉当（NC）的几何形状。我们进一步构造相应的单峰矩阵，从而在严格的NC背景下导致无限个非局部守恒电荷塔。
