Title: Construction and enlargement of dilatonic wormholes by impulsive
radiation
Authors: Hiroko Koyama, Sean A. Hayward, Sung-Won Kim
Comments: 6 pages and 8 figures
The dynamical behavior of traversable wormholes and black holes under
impulsive radiation is studied in an exactly soluble dilaton gravity model.
Simple solutions are presented where a traversable wormhole is constructed
from a black hole, or the throat of a wormhole is stably enlarged or reduced.
These solutions illustrate the basic operating principles needed to construct
similar analytic solutions in full Einstein gravity.
