摘要：

By use of wave packets and a push-forwards, we build a model for Toeplitz operators. This model is achived as the composition of the operator of multiplication by a function followed by a fixed projector. We define next a natural notion of total symbol for Toeplitz operators and we show that a sufficient condition to a Toeplitz operator to be positive is that its total symbol is nonnegative. Sharp Garding inequality of any order follows from that.
