Abstract
The Cheeger's inequalities and some existence criteria for spectral ga p and for general symmetric forms are established. The criteria are al so extended to general reversible Markov processes but not reported he re. Even though in the past several decades, the topics have been wide ly studied, as far as we know the first problem in the unbounded case and the second one in the general case remain open.
