In this paper, we study a category of restricted modules for the Ovsienko-Roger algebra, which is an extension of the Virasoro algebra of its tensor density module of degree one. We construct and characterize simple modules in this category and give natural free field realizations of certain restricted modules using the Weyl vertex algebra.

Ovisenko-Roger代数的一类受限模块

在本文中，我们研究了Ovsienko-Roger代数的受限模的一类，这是Virasoro代数对其一阶张量密度模的扩展。我们构造和表征此类别中的简单模块，并使用Weyl顶点代数给出某些受限模块的自然自由域实现。
