abstract
Let $\mathscr{F}$ be a family of graphs. A graph $G$ is $\mathscr{F}$-free if $G$ does not contain any $F\in \mathcal{F}$ as a subgraph. The general Tur\'an number, denoted by $ex(n, H,\mathscr{F})$, is the maximum number of copies of $H$ in an $n$-vertex $\mathscr{F}$-free graph. Then $ex(n, K_2,\mathscr{F})$, also denote by $ex(n, \mathscr{F})$, is the Tur\'an number. Recently, Alon and Frankl determined the exact value of $ex(n, \{K_{k},M_{s+1}\})$, where $K_{k}$ and $M_{s+1}$ are a complete graph on $k $ vertices and a matching of size $s +1$, respectively. Then many results were obtained by extending $K_{k}$ to a general fixed graph or family of graphs. Let $C_k$ be a cycle of order $k$. Denote $C_{\ge k}=\{C_k,C_{k+1},\ldots\}$. In this paper, we determine the value of $ex(n,K_r, \{C_{\ge k},M_{s+1}\})$ for large enough $n$ and obtain the extremal graphs when $k$ is odd. Particularly, the exact value of $ex(n, \{C_{\ge k},M_{s+1}\})$ and the extremal graph are given for large enough $n$.

Spectral extremal problems for degenerate graphs
For finite degenerate graph families with linear ex(n,F), the spectral extremal graph is characterized by the independent covering number β'(F) and the induced family H(F).
