This monograph presents a short course in computational geometry and
topology. In the first part the book covers Voronoi diagrams and
Delaunay triangulations, then it presents the theory of alpha complexes
which play a crucial role in biology. The central part of the book is
the homology theory and their computation, including the theory of
persistence which is indispensable for applications, e.g. shape
reconstruction. The target audience comprises researchers and
practitioners in mathematics, biology, neuroscience and computer
science, but the book may also be beneficial to graduate students of
these fields.
