Using the results of [1]–[3] on Kählerian K3 surfaces and Niemeier lattices, we classify degenerations of Kählerian K3 surfaces with finite symplectic automorphism groups with emphasis on degenerations of codimension 1.
Keywords: K3 surface, Kählerian surface, degeneration, singularities, Picard lattice, integral quadratic form.
Mots-clés : automorphism group
