The Virtual Goniometer: A new method for measuring angles on 3D models of fragmentary bone and lithics
Katrina Yezzi-Woodley, Jeff Calder, Peter J. Olver +7
The contact goniometer is a commonly used tool in lithic and zooarchaeological analysis, despite suffering from a number of shortcomings due to the physical interaction between the…
New Revival Phenomena for Linear Integro-Differential Equations
Lyonell Boulton, Peter J. Olver, Beatrice Pelloni +1
We present and analyse a novel manifestation of the revival phenomenon for linear spatially periodic evolution equations, in the concrete case of three nonlocal equations that aris…
Feature Matching and Heat Flow in Centro-Affine Geometry
Peter J. Olver, Changzheng Qu, Yun Yang
In this paper, we study the differential invariants and the invariant heat flow in centro-affine geometry, proving that the latter is equivalent to the inviscid Burgers' equation.…
