Resumen:
We will present a proof of a recent theorem of R. Berger and V. Ginzburg
giving necessary and sufficent conditions for a non-homogeneous
deformation of a Koszul algebra to be a Poincaré-Birkhoff-Witt
deformation. Our approach is purely cohomological, using the classical
deformation theory developed by M. Gerstenhaber in terms of Hochschild
cohomology.
