摘要：

We shall consider on spaces that have no continuous selections. We shall prove the following. (1) Every regular space admitting a continuous selection is hereditarily Baire. (2) There exists no continuous selection on the subspace of 2(Q) consisting of clopen sets of Q. (3) Assuming the continuum hypothesis there exists a Bernstein set admitting no continuous selection.
