具有负范数玻色子和无屏蔽电荷的刘维理论对应于描述含时体快子凝聚的闭玻色弦理论的精确经典解。基于普通（正范数）Liouville理论的已知结果的重整化/解析延拓，提出了两点函数的一个简单表达式。这个表达式与闭弦对产生率（在有限时刻发散）的小超空间结果完全一致。提出并讨论了关于三点函数的问题。
Liouville theory with a negative norm boson and no screening charge corresponds to an exact classical solution of closed bosonic string theory describing time-dependent bulk tachyon condensation. A simple expression for the two point function is proposed based on renormalization/analytic continuation of the known results for the ordinary (positive-norm) Liouville theory. The expression agrees exactly with the minisuperspace result for the closed string pair-production rate (which diverges at finite time). Puzzles concerning the three-point function are presented and discussed.
