In the first part of the talk I will explain the classification of complete simply connected Riemannian manifolds carrying a metric connection whose torsion is parallel\, has non-zero vectorial com ponent and vanishing twistorial component. In the second part I will desc ribe the case where the only non-vanishing component of the torsion is tot ally skew-symmetric. Although apparently simpler than the previous case\, the situation here is much more involved and a complete classification is currently not available. The talk is based on joint works with Mihaela Pil ca and Uwe Semmelmann.\n LOCATION:https://researchseminars.org/talk/DGSTO/15/ END:VEVENT END:VCALENDAR
