We define a partial order on the set No,c̄ of pairs (O, C), where O is a nilpotent orbit and C is a conjugacy class in Ā(O), Lusztig’s canonical quotient of A(O). We then show that there is a unique order-reversing duality map No,c̄ → LNo,c̄ that has certain properties analogous to those of the original Lusztig-Spaltenstein duality map. This generalizes work of E. Sommers.

The paper describes a new tagset for the morphological disambiguation of Sanskrit, and compares the accuracy of two machine learning methods (CRF, deep recurrent neural networks) for this task, with a special focus on how to model the lexicographic information. It reports a significant improvement over previously published results. 1 Challenges of Sanskrit Linguistics and Related Research Class...

Causality has been recently introduced in databases, to model, characterize and possibly compute causes for query results (answers). Connections between query causality and consistency-based diagnosis and database repairs (wrt. integrity constrain violations) have been established in the literature. In this work we establish connections between query causality and abductive diagnosis and the vi...

Hebrew has no multiple nominative construction (MNC) of the Japanese type, contrary to the claims of three recent studies. The alleged ‘‘broad subject’’ in the Hebrew constructions is nothing but a left-dislocated DP. A series of arguments is presented to the effect that this DP patterns with Ā-bar phrases and displays none of the subject properties characteristic of either standard or broad su...
