Abstract: | We have rigorously solved the standard BCS gap equation with the density of states of Van Hove type. The result shows that the enhancement ofT
c
is not as effective as previously estimated. It seems unlikely that Van Hove singularity inN(E) can be theT
c
-enhancement mechanism for the high-T

Cu oxides. |
