報告題目：On the spectral radius of graphs without linear forests and star forests
報告人：陳明珠
邀請人：劉樂樂
摘要：The Tur\'an type problems ask to maximize the number of edges over all graphs which do not contain a graph $F$ as a subgraph. Similarly, their spectral counterparts ask to maximize the spectral radius of all graphs which do not contain a graph $F$ as a subgraph. In this talk, we present the sharp upper bounds of the spectral radius of all graphs which do not contain a linear forest and a star forest as a subgraph and characterize all the extremal graphs attaining the upper bounds, respectively.
