RELATIVE A1-CONTRACTIBILITY OF SMOOTH SCHEMES AND EXOTIC MOTIVIC SPHERES
Uno dei problemi emergenti nella geometria algebrica è quello di caratterizzare lo spazio affine n-dimensionale A^n tra schemi affini regolari a meno di A^1-contrazione: una proprietà che rende gli spazi motivici omotopicamente equivalenti a un campo Spec k nella teoria dell'omotopia motivica. …

DEGENERATIONS OF AUTOMORPHISMS ON IRREDUCIBLE HOLOMORPHIC SYMPLECTIC VARIETIES
The aim of this thesis is to study the degeneration of special automorphisms (termed non-symplectic) on certain families of irreducible holomorphic symplectic varieties (IHS varieties).\newline\newline In fact, the moduli space of smooth cubic threefolds is isomorphic to a moduli space …
