Extension Condition "violations" and Merge optimality constraints

扩展条件“违反”与合并最优约束

Matilde Marcolli, Richard Larson, Riny Huijbregts

机构 * Department of Mathematics(数学系) Department of Computing(计算系) Mathematical Sciences, California Institute of Technology, CA 91125, USA(数学科学,加州理工学院) Department of Linguistics, Stony Brook University, NY 11794-4376, USA(语言学系,石溪大学) Department of Linguistics, Utrecht University, Trans 10, 3512 JK Utrecht, The Netherlands(语言学系,乌得勒支大学)

AI总结 本文通过侧向合并解释多种语言现象,展示扩展条件并非必要,且最优性违反在模型中具有结构代数作用。
