He has created an entirely new and exciting area of research through which much of mathematics passes and which continues to yield mysterious and unexpected phenomena about the topology and geometry of smooth 4-manifolds.
Siya ay lumikha ng isang bagong buo at nakapupukaw na lugar sa pamamagitan ng pananaliksik na kung saan marami ng matematika at lipas na patuloy na ani kataka-taka at di-inaasahang phenomena tungkol sa mga topology at geometry ng makinis 4-manifolds.
