The nonperturbative aspects of string theory are explored for noncritical string in two distinct formulations, loop equations and matrix models. Theeffects corresponding to the D-brane in these formulations are especially investigated in detail. ﾊIt is shown that matrix models can universally yield a definite value of the chemical potential for an instanton while loop equations cannot. This implies that it may not be possible to formulate string theory nonperturbatively solely in terms of closed strings. If there is time, we also discuss nonperturbative effect in type 0 string theory and related problems. |
