Zero-dimensional Shimura varieties and central derivatives of Eisenstein series
Siddarth Sankaran
We formulate and prove a version of the arithmetic Siegel-Weil formula for (zero dimensional) Shimura varieties attached to tori, equipped with some additional data. More precisely…

Grain boundary diffusion and grain boundary structures of a Ni-Cr-Fe-alloy: Evidences for grain boundary phase transformations
Sai Rajeshwari K, S. Sankaran, K. C. Hari Kumar +4
Grain boundary tracer diffusion of Ni, Fe and Cr was studied in a Ni-base 602CA coarse-grained alloy. A co-existence of several short-circuit contributions was distinguished at hig…

Green forms and the arithmetic Siegel-Weil formula
Luis E. Garcia, Siddarth Sankaran
We construct natural Green forms for special cycles in orthogonal and unitary Shimura varieties, in all codimensions, and, for compact Shimura varieties of type O(p,2) and U(p,1),…
