Weighted moments and sharp convergence rates for supercritical multitype branching processes

Sheng Xiao, Yingqiu Li, Xingang Liang

Let $Z_n^i=(Z_n^i(1),\cdots ,Z_n^i(d)),n⩾0$, be a supercritical $d$-type branching process starting from a single particle of type $i\in \{1,\cdots ,d\}$, where $d$ is a posi…
