报告摘要：
In 1990, Cvetkovi´c and Rowlinson conjectured that among all outerplanar graphs on n vertices, K1∨Pn−1 attains the maximal spectral radius. Very recently, Tait and Tobin confirmed this conjecture for sufficiently large graphs. In this talk, we first survey several results about planarity of graphs in spectral graph theory. We mainly give a sketch of a proof of this conjecture for n ≥ 17.
