Abstract: In this talk we discuss new constructions via non-reductive GIT of del Pezzo surfaces of degree 1 and 2 coming from the description as surfaces in weighted projective 3-folds. For degrees 1, 2 and 3 we discuss stratifications coming from GIT and compare these with geometric stratifications given by singularity type.
