中文简介:
与图相关的拉普拉斯算子有两个不同的概念:度量图(广泛称为量子图)上的离散图拉普拉斯算子和连续拉普拉斯算子。这两个物体都有着悠久的历史,因为它们与数学和数学物理的几个不同分支有关。现有文献通常分别处理这两个拉普拉斯算子。在这次演讲中,我将重点讨论它们之间的关系(光谱性质、抛物性质和几何性质)。我们的一个主要概念信息是,这两种环境应该被视为互补的(而不是相反的),它们的相互作用正是导致双方进一步深入了解的重要原因。基于与Noema Nicolussi的联合工作。
课程简介: There are two different notions of a Laplacian operator associated with graphs: discrete graph Laplacians and continuous Laplacians on metric graphs (widely known as quantum graphs). Both objects have a venerable history as they are related to several diverse branches of mathematics and mathematical physics. The existing literature usually treats these two Laplacian operators separately. In this talk, I will focus on the relationship between them (spectral, parabolic and geometric properties). One of our main conceptual messages is that these two settings should be regarded as complementary (rather than opposite) and exactly their interplay leads to important further insight on both sides. Based on joint work with Noema Nicolussi.
