1) voltage group
电压群
1.
A new method is used to discuss the connected coverings of graph K6 with the voltage group Z42,and we find that there are no 2-transitive regular connected coverings of K6 satisfying the following two conditions:the covering transformation group is isomorphic to Z42,andthe fibre-preserving automorphism subgroup acts 2-arc-transitively on the graph Γ~=Γ×A.
讨论了图K6的电压群为224的连通拓扑覆盖图,发现图K6没有具有以下条件的连通正则拓扑覆盖图:拓扑覆盖传递群同构于224;保持束不变自同构子群G2-弧传递的作用于图Γ~。

1.
In this paper,we show that the geometric catastrophe q-matrix Q generates a positive contraction integrated semigroup on l∞,Q also generates a continuous contraction semigroup on c0 and the minimal Q-function P(t) is always a Felle-Reuter-Riley function,and establish a criterion for stochastic monotonicity.
