# Alterman Summer School on Geometric Algebra and Kähler Calculus 2017

The Alterman Summer School on Geometric Algebra and Kähler Calculus 2017 deals mainly with Clifford (geometric) algebra and the Kähler calculus based on (but not only) Clifford algebra of differential forms. Erich Kähler developed this calculus by joining Clifford's geometric algebra and Cartan´s exterior calculus. The Kähler calculus has immediate application to many branches of physics, especially quantum mechanics, whose foundations it affects.

The Alterman events are becoming a series of periodic conferences and summer schools sponsored by Mr. Eric Alterman. Thanks to his support, fees are unexpensive (150€ and 50€ for shared lodging). Students have a reduced fee (75€) and free shared lodging. The contents of the lectures and the unexpensive fees provide an unusual learning opportunity. This year is the second edition. The first edition (Alterman Conference 2016) was held in Brasov (Romania).
