U.S.-Argentina Planning Visit on Hochschild and Cyclic Homology

小行星9600366 PI将对阿根廷的布宜诺斯艾利斯和拉普拉塔进行规划访问，与G。 拉普拉塔大学和O.布宜诺斯艾利斯大学的Villamayor在Hochschild和循环同源性领域。 PI已经与Cortinas一起出版，并将与Villamayor和他的“BACH”小组在他们的重叠利益范围内寻求新的方向。一个猜想感兴趣的所有三个是是否跟踪地图的代数K理论的Q代数其Hochschild同调保持分解所给予的亚当斯业务;另一个，归因于伯杰，涉及模块的Kaehler微分的一个正规环。 合作者在建议的领域进行积极的研究计划，解决的问题是该领域的重要问题。 这次访问将为制定一项利用三位研究人员共同努力的明确计划提供机会。 ***

9600366 Weibel The PI will conduct a planning visit to Buenos Aires and La Plata, Argentina to establish a collaboration with G. Cortinas of Universidad de La Plata and O. Villamayor of Universidad de Buenos Aires in the area of Hochschild and cyclic homology. The PI has already published with Cortinas and will seek new directions with Villamayor and his "BACH" group within their overlapping interests. One conjecture of interest to all three is whether the trace map from the algebraic K-theory of a Q-algebra to its Hochschild homology preserves the decomposition given by Adams operations; another, attributed to Berger, deals with the module of Kaehler differentials over a regular ring. The collaborators conduct active research programs in the proposed areas and the questions addressed are important ones to the field. The visit will provide the opportunity to establish a clear plan to take advantage of the combined efforts of the three researchers. ***
