摘要：

The cosmological term is formulated in the framework of the extended loop representation and its particularization from the extended loop to the loop representations is given. The properties of the Gauss self-linking number are investigated. It is shown that the phase factor of the Kauffman bracket satisfies the Mandelstam identities, the diffeomorphism constraint and the Hamiltonian constraint with the cosmological constant in the extended loop calculus.
