We show how to maintain the width of a set of n planar points subject to insertions and deletions of points in O( n log3 n) amortized time per update. Previously, no fully dynami...

We show the first o(n2 ) algorithm for coloring vertices of trianglefree planar graphs using three colors. The time complexity of the algorithm is O(n log n). Our approach can be ...
