In this paper, we construct defects (domain walls) that connect different phases of two-dimensional gauged linear sigma models (GLSMs), as well as defects that embed those phases into the GLSMs. Via their action on boundary conditions these defects give rise to functors between the D-brane categories, which respectively describe the transport of D-branes between different phases, and embed the D-brane categories of the phases into the category of D-branes of the GLSMs.

GLSM和缺陷中的相变

在本文中，我们构造了连接二维规范线性sigma模型（GLSM）不同相的缺陷（畴壁），以及将这些相嵌入GLSM中的缺陷。通过它们对边界条件的作用，这些缺陷在D膜类别之间产生了函子，这些函子分别描述了D相在不同相之间的迁移，并将相的D膜类别嵌入了D相的D核类别中。 GLSM。
