This quantity attests to the power of differential geometry because it probes deeper into its inner constitution and explores ever widening connections with different topics in arithmetic and physics. To so much folks Professor S. S. Chern is sleek differential geometry, and we, his scholars, are thankful to him for prime us to this fertile panorama. The goals of the symposium have been to study fresh advancements in geometry and to show and discover new components of study. It used to be our approach of honoring Professor Chern upon the party of his reliable retirement as Professor of arithmetic on the collage of California. This publication is a list of the clinical occasions of the symposium and displays Professor Chern's broad curiosity and effect. The convention additionally mirrored Professor Chern's character. It used to be a major social gathering, energetic but secure, combined with gentleness and reliable humor. we want him strong future health, a longevity, happiness, and a continuation of his terribly deep and unique contributions to arithmetic.

2) -00 From the spectral decomposition of Kp, one deduces, for either value of v, that the integral above converges, that J p commutes with Kp, and that J p maps Isometric Families of Kimler Structures 29 T' and T" each bijectively onto the other, so that Furthermore (v = 1,2), J~=~-IJ;, and both J I and J 2 have vanishing covariant derivatives with respect to the metric, so that they define integrable complex analytic structures with respect to the metric, and the metric is Kahlerian with respect to either of the two resulting new complex structures.
