Spacetime singularities in string theory
Physical Review Letters, 1990Summary: It is shown that a large class of time-dependent solutions to Einstein's equation are classical solutions to string theory. These include metrics with large curvature and some with spacetime singularities. Unlike the case of orbifold singularities, it is shown that string propagation through the singluar region is not well behaved.

Singularities and the geometry of spacetime
The aim of this essay is to investigate certain aspects of the geometry of the spacetime manifold in the General Theory of Relativity with particular reference to the occurrence of singularities in cosmological solutions and their relation with other global properties. Section 2 gives a brief outline of Riemannian geometry.

Quantum healing of spacetime singularities: A review
Singularities are commonplace in general relativistic spacetimes. It is natural to hope that they might be “healed” (or resolved) by the inclusion of quantum mechanics, either in the theory itself (quantum gravity) or, more modestly, in the description ...

Strengths of singularities in Vaidya spacetimes
Physical Review D, 1987The strengths of shell-focusing singularities in the ingoing Vaidya spacetimes are examined in terms of limiting focusing conditions. The singularities are found to be strong-curvature singularities only for mass functions which are initially linear functions of the advanced time.

Strings falling into spacetime singularities
Physical Review D, 1992We study the dynamics of strings near spacetime singularities. We consider gravitational-wave backgrounds with a singularity of the type {vert bar}{ital U}{vert bar}{sup {minus}{beta}}, {ital U} being a null coordinate. (The case with a {delta}({ital U}) shock-wave singularity turns out to be similar to the {beta}=1 case.) New features in the string ...
