VIII International Colloquium on Differential Geometry
Santiago de Compostela, 7-11 July 2008
Fourth Colloquium

Held from 18 to 21 of September, 1978, this fourth edition of the series of Colloquia has been specially dedicated to celebrate the 70th anniversary of Prof. E. Vidal Abascal as well as his academic retirement.

There were 46 participants coming from 8 different countries (Argentine, Belgium, France, Germany, Great Britain, Spain, Switzerland and United States). There were 7 plenary lectures by invitation, and the invited lecturers were J. Eells (Great Britain), A. Gray (USA), A. Haefliger (Switzerland), A. Lichnerowicz (France), G. Reeb (France), B.L. Reinhart (USA) and L.A. Santaló (Argentine).

Again, the proceedings of this Colloquium were published in the series “Cursos e Congresos” of the University of Santiago de Compostela in 1979. A total of 27 conferences and/or communications are collected in these proceedings. The reference of this publication is the following:
