Description
Summary:This dissertation is devoted to the study of black hole and
p-brane solutions and dualities in string theory. Strong
evidence is presented that certain massive string states can
be identified with extremal black holes. The degeneracy of
these string states hints at a non-vanishing Beckenstein-
Hawking entropy in contrast to the classical black hole
analysis which reveals zero entropy. This discrepancy might
be cured by quantum effects. In fact it is shown that taking
loop corrections into account one finds that arbitrary p-
branes in the near-extremal limit obey the
entropy/temperature relationship of a massless ideal gas in p
dimensions as expected from an open string D-brane
description. For the special case p = 0 this result is
consistent with a nonvanishing entropy of extremal black
holes as indicated by string state counting. The four-
dimensional extremal black holes also fit naturally into a
string/string/string triality in four dimensions that relates
the heterotic string compactified on a six-torus and the Type
IIA and IIB strings compactified on K3 x T'. The
implications of this interconnection between these different
string theories are studied.
