We study harmonic maps from surfaces coupled to a scalar and a two-form potential, which arise as critical points of the action of the full bosonic string. We investigate several analytic and geometric properties of these maps and prove an existence result by the heat-flow method.

完整玻色弦的热流

我们研究了耦合到标量和双形式势的表面的谐波映射，它们作为完整玻色弦作用的关键点出现。我们研究了这些地图的几个解析和几何特性，并通过热流方法证明了存在性结果。
