Harmonic Functions and Collision Probabilities
1997
The international journal of robotics research
Preserved Fulltext
In short, the hitting probabilities for random walks can be cast as a Dirichlet problem for harmonic functions, in much the same way as in path planning. ...
This paper describes a relationship between harmonic functions { which have recently been proposed for path planning { and recent work on randomization and learning in robotics. ...
In this case, the resulting harmonic function is the collision probability function over the workspace. ...

A selection of recent results from two and three particle correlations measured by the ALICE experiment are presented, and some brief interpretations of their implications are offered. ...
Peaks in a correlation function indicate a relatively high probability for particle coincidence in a particular region of phase space for the pair; accordingly, depletions indicate a lower probability. ...
