1 We present a solution to the conjugacy decision problem and the conjugacy search problem2 in Garside groups, which is theoretically simpler than the usual one, with no loss of eï...

We introduce a method for computing homology groups and their generators of a 2D image, using a hierarchical structure i.e. irregular graph pyramid. Starting from an image, a hiera...
