Abstract: In this talk, we show how to apply the original $L^2$-extension theorem of Ohsawa and Takegoshi to the Gröbner basis of a multiplier ideal sheaf associated with a plurisubharmonic function. In this way, we are able to reprove the strong openness conjecture and to obtain an effective version of the semicontinuity theorem for weighted log canonical thresholds.
