Regular Linear Time Varying DAEs are Equivalent to DAEs in Strong Standard Canonical Form

The relationship between solvability of linear diffential-algebraic equations (DAEs) and their transformability into canonical forms has been investigated for more than forty years. After a comparative analysis of numerous DAE frameworks the notions regularity and almost regulari...

Two Surfaces of Ambiguity: Complementary Detection for Text-to-SQL

Natural-language interfaces to relational databases increasingly rely on LLMs, but real-world queries are routinely ambiguous, admitting multiple valid SQL interpretations. In interactive deployment, the system should detect this ambiguity and ask for clarification rather than co...
