Summary
We prove several sharp inequalities specifying the uniform convexity and uniform smoothness properties of the Schatten trace idealsC p , which are the analogs of the Lebesgue spacesL p in non-commutative integration. The inequalities are all precise analogs of results which had been known inL p , but were only known inC p for special values ofp. In the course of our treatment of uniform convexity and smoothness inequalities forC p we obtain new and simple proofs of the known inequalities forL p .
