Title: Moduli of low degree del Pezzo surfaces and stratifications


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.
