چکیده
|
We analyze different approaches to quantum gravity. it is stressed that nonperturbative methods to quantise gravity and the usage of diffeomorphism-invariant variables are very important. we pay attention on the wheeler--dewitt equation in the framework of canonical quantum gravity. the wheeler--dewitt equation is presented in the first order formalism with the hope that this form can solve some problems such as singularities and the ordering. also, there is a problem of defining the time.
