Here, the torsion tensor is obtained from metricity condition for the connection and the static spinor field is determined as the solution of Dirac equation in 2+1 spacetime with non-zero cosmological constant and torsion. The torsion itself is considered as a non-dynamical field.6 pagesGeneral Relativity and Quantum Cosmology2+1 dimensional solution of Einstein Cartan equationstext
