Bessel Inequality and the Basis Property for a Dirac Type System with an Integrable Potential

Bessel Inequality and the Basis Property for a Dirac Type System with an Integrable Potential

We study the Bessel and basis properties of root vector functions of a Dirac type operator with an integrable potential. Criteria for the Bessel and basis properties are established, and a theorem on the equivalent basis property in is proved.
