  Automated Deduction in Geometry (ADG) is a forum to exchange ideas and views,
to present research results and progress, and to demonstrate software tools at
the intersection between geometry and automated deduction. Relevant topics
include (but are not limited to): polynomial algebra, invariant and
coordinate-free methods; probabilistic, synthetic, and logic approaches,
techniques for automated geometric reasoning from discrete mathematics,
combinatorics, and numerics; interactive theorem proving in geometry; symbolic
and numeric methods for geometric computation, geometric constraint solving,
automated generation/reasoning and manipulation with diagrams; design and
implementation of geometry software, automated theorem provers, special-purpose
tools, experimental studies; applications of ADG in mechanics, geometric
modelling, CAGD/CAD, computer vision, robotics and education.
  Traditionally, the ADG conference is held every two years. The previous
editions of ADG were held in Nanning in 2018, Strasbourg in 2016, Coimbra in
2014, Edinburgh in 2012, Munich in 2010, Shanghai in 2008, Pontevedra in 2006,
Gainesville in 2004, Hagenberg in 2002, Zurich in 2000, Beijing in 1998, and
Toulouse in 1996. The 13th edition of ADG was supposed to be held in 2020 in
Hagenberg, Austria, but due to the COVID-19 pandemic, it was postponed for
2021, and held online (still hosted by RISC Institute, Hagenberg, Austria),
September 15-17, 2021 (https://www.risc.jku.at/conferences/adg2021).
