摘要：

In this paper we determine the group of endotrivial modules for certain symmetric and alternating groups in characteristic p. If p = 2, then the group is generated by the class of Omega(n) (k) except in a few low degrees. If p > 2, then the group is only determined for degrees less than p(2). In these cases we show that there are several Young modules which are endotrivial.
