5. BLACK HOLE SOLUTIONS<br />

Now we come to spherically symmetric case of (31), i.e. we put<br />

where is the metric on a unit sphere<br />

We put i.e. is<br />

a time manifold. We also assume that <strong>and</strong><br />

These solutions conta<strong>in</strong> the black hole ones [10, 11, 12]:
