Non-critical non-singular bosonic strings, linear dilatons and holography Original Research Article

AdS5 with linear dilaton and nonvanishing B-field is shown to be a solution of the noncritical string beta function equations. A noncritical (D=5) solution interpolating between flat spacetime and AdS5, with asymptotic linear dilaton and nonvanishing B-field is also presented. This solution is free of spacetime singularities and has got the string coupling constant everywhere bounded. Both solutions admit holographic interpretation in terms of N=0 field theories. Closed string tachyon stability is also discussed.
