Abstract
We consider a Dirac type operator with matrix coefficients. Estimates for the root vector
functions are established, and criteria for the Bessel property and the unconditional basis property
of the root vector function systems of this operator in the space \(L_{2}^{2m}(G) \), where \(G=(a,b)\subset \mathbb {R} \) is a finite interval, are obtained.
