连续时间连续空间出生过程的渐近形状和传播速度

Asymptotic shape and the speed of propagation of continuous-time continuous-space birth processes

Viktor Bezborodov, Luca Di Persio, Tyll Krueger, Mykola Lebid, Tomasz Ożański

摘要:

在一定的一般条件下,给出并证明了连续时间连续空间随机增长模型的形状定理。类似于经典的晶格生长模型的证明利用次加性遍历定理。在截断自由分支出生率的情况下,给出了传播速度的精确表达式。

英文摘要:

We formulate and prove a shape theorem for a continuous-time continuous-space stochastic growth model under certain general conditions. Similarly to the classical lattice growth models the proof makes use of the subadditive ergodic theorem. A precise expression for the speed of propagation is given in the case of a truncated free branching birth rate.
