Fully dynamic maintenance of Euclidean minimum spanning trees and maxima of decomposable functions [PDF]

, 1992
We maintain the minimum spanning tree of a point set in the plane, subject to point insertions and deletions, in time O(n^1/2 log^2 n) per update operation. We reduce the problem to maintaining bichromatic closest pairs, which we solve in time O(n^E) per

Appearance Enhancement for Visually Impaired with Projector Camera Feedback [PDF]

, 2010
Visually impaired is a common problem for human life in the world wide. The projector-based AR technique has ability to change appearance of real object, and it can help to improve visibility for visually impaired.

The Interlace Polynomial

, 2016
In this paper, we survey results regarding the interlace polynomial of a graph, connections to such graph polynomials as the Martin and Tutte polynomials, and generalizations to the realms of isotropic systems and delta-matroids.Comment: 18 pages, 5 ...

Spanning Trees on Graphs and Lattices in d Dimensions

, 2000
The problem of enumerating spanning trees on graphs and lattices is considered. We obtain bounds on the number of spanning trees $N_{ST}$ and establish inequalities relating the numbers of spanning trees of different graphs or lattices.

Partition function of the Potts model on self-similar lattices as a dynamical system and multiple transitions

, 2010
We present an analytic study of the Potts model partition function on two different types of self-similar lattices of triangular shape with non integer Hausdorff dimension.
