Key Points
This research investigates the relationship between normalized volume and the boundedness of different classes of singularities.
Proved the boundedness of K-semistable threefold singularities with normalized volume at least v>0.
Demonstrated analogous results for n-dimensional complexity-1 and n-dimensional hypersurface singularities.
Showed that, for klt singularities, normalized volume bounds complexity-1 singularities with special degenerations.
Established that K-semistable threefold singularities with normalized volume v form a bounded family.
Proved similar statements for complexity-1 and hypersurface singularities in n dimensions.
Exhibited a 3-dimensional example illustrating the optimality of the results regarding klt singularities.
