Supersaturation thresholds for expanded color-critical graphs

Liping Zhang, Qinghai Liu, Yanmei Hong +2

For a $k$ -uniform hypergraph $L$ , let $h_{L} (n, q)$ be the minimum number of copies of $L$ in an $n$ -vertex $k$ -graph with $ex (n, L) + q$ edges. Let $t_{L} (n, q)$ be the minimum nu…

Divergent Evolution of Radial Metallicity Gradients in the Thin and Thick Disks of the Milky Way

Weixiang Sun, Gaohuan Long, Hui Li +6

Using 200,388 red clump stars from LAMOST and APOGEE, we investigate the radial metallicity gradients of the Galactic disk as a function of vertical height and stellar age. The thi…
