Gorenstien Projective Precovers

We consider a right coherent and left n-perfect ring R. We prove that the class of Gorenstein projective complexes is special precovering in the category of unbounded complexes, Ch(R). As a corollary, we show that the class of Gorenstein projective modules is special precovering over such a ring.  This is joint work with Sergio Estrada and Sinem Odabasi.
