Partial Elastic Shape Registration of 3D Surfaces using Dynamic Programming
Javier Bernal, Jim Lawrence
The computation of the elastic shape registration of two simple surfaces in 3-dimensional space and therefore of the elastic shape distance between them has been investigated by Ku…
Power-closed ideals of polynomial and Laurent polynomial rings
Geir Agnarsson, Jim Lawrence
We investigate the structure of power-closed ideals of the complex polynomial ring and the Laurent polynomial ring $R^{\pm} = \mathbb{C}[x_1,\ldots…
Homotheties and Coverings by Convex Sets
Jim Lawrence
It is shown that, for any function that is weakly increasing on compact convex sets and has the property that if and is a translate of then $g(K^\prime…
Gegenbauer expansions and addition theorems for a binomial and logarithmic fundamental solution of the even-dimensional Euclidean polyharmonic equation
Howard S. Cohl, Jessie E. Hirtenstein, Jim Lawrence +1
On even-dimensional Euclidean space for integer powers of the Laplace operator greater than or equal to half the dimension, a fundamental solution of the polyharmonic equation has…
Cubes and adjoints of cross-polytopes
J. Lawrence, I. P. Silva
We describe a bijection between oriented cubes and adjoints of cross-polytopes. This correspondence is used to prove that the real affine cube is, up to reorientation in the same c…
Characterization and Computation of Matrices of Maximal Trace over Rotations
Javier Bernal, Jim Lawrence
The constrained orthogonal Procrustes problem is the least-squares problem that calls for a rotation matrix that optimally aligns two corresponding sets of points in d-dimensional…
