Summary: | In 17 refereed papers, researchers from around the world explore some of the most advanced topics of gravitation theory, including antigravitating bubbles, a possible solution to the problem of extra dimensions, affine-metric gravity with the projective invariance, teleparallelism and geometrodynamics, and why all the curvature invariants of a gravitational wave vanish. The field continues to be dominated by efforts to quantize gravity and to unify it with other fundamental forces. No index. Annotation c. by Book News, Inc., Portland, Or.
