NONEXTREME BLACK-HOLES FROM INTERSECTING M-BRANES

We investigate the possibility of extending nonextreme black hole solu tions made of intersecting M-branes to those with two nonextreme defor mation parameters, similar to Reissner-Nordstrom solutions. General an alysis of possible solutions is carried out to reduce the problem of s olving field equations to a simple algebraic one for static sphericall y-symmetric case in D dimensions. The results are used to show that th e extension to two-parameter solutions is possible for D = 4, 5 dimens ions but not for higher dimensions, and that the area of horizon alway s vanishes in the extreme limit for black hole solutions for D greater than or equal to 6 except for two very special cases which are identi fied. Various solutions are also summarized.
