| Research Abstract |
A group G is said to have rigidity, if the space accepting the action of G is very restrictive. A group G is said to have fixed-point property for a space Y, if every action of G fixes a point in Y. Recent development of mathematical research suggests that there are plenty of groups having rigidity. We proved that, in a certain model, groups have strong fixed-point property with high probability.
