概要
We prove that partial type reconstruction for the pure polymorphic λ-calculus is undecidable by a reduction from the second-order unification problem, extending a previous result by H.-J. Boehm. We show further that partial type reconstruction remains undecidable even in a very small predicative fragment of the polymorphic λ-calculus, which implies undecidability of partial type reconstruction for λML as introduced by Harper, Mitchell, and Moggi. λ ^[$@&K^[(J^[$@&K^[(J^[$@&K^[(J^[$@&K^[(J^[$@&K^[(J^[$@&K^[(J

Abstract: We prove that partial type reconstruction for the pure
        polymorphic λ-calculus is undecidable by a reduction 
        from the second-order unification problem, extending a previous
        result by H.-J. Boehm.
        We show further that partial type reconstruction remains 
        undecidable even in a very small predicative fragment of the 
        polymorphic λ-calculus, which implies undecidability 
        of partial type reconstruction for λML as introduced 
        by Harper, Mitchell, and Moggi.
