<div align="justify"><font color="#ff0000"><font
color="#000000">The classical Kummer construction
associates a K3 surface to any 2-dimensional complex
torus. In my talk I will present an analogue of this
construction, which involves the two most well-studied
deformation types of hyper-Kähler manifolds in
dimension 6. Namely, starting from any hyper-Kähler
sixfold K of generalized Kummer type, I am able to
construct geometrically a hyper-Kähler manifold of
K3[3]-type. When K is projective, the associated
variety is birational to a moduli space of sheaves on
a uniquely determined K3 surface. As application of
this construction I will show that the Kuga-Satake
correspondence is algebraic for many K3 surfaces of
Picard rank 16.</font></font></div>
