Constrained type families

J. Garrett Morris, Richard A. Eisenberg
2017 Proceedings of the ACM on Programming Languages  
However, their current design implicitly assumes that type families are total, introducing nonsensical types and significantly complicating the metatheory of type families and their extensions.  ...  For example, type families in Haskell provide a powerful, modular means of defining type-level computation.  ...  Validating Constrained Type Families In the previous section, we introduced an intuitive characterization of constrained type families.  ...

Private Tutoring, Wealth Constraint and Higher Education

Hsiao-Lei Chu
2015 Pacific Economic Review  
At the same time, the average spending on PT of the poor families is smaller than that of the rich families.  ...  We show that when the effectiveness of private tutoring (PT) exceeds a PTeffectiveness threshold, poor families become disadvantaged in sending their children to college and, thus, inequity arises.  ...  In sum, if  * *     * * * then student loans eliminate the inequity issue and no type- families are wealth-constrained, however, if    * * * type- families are still wealth-constrained even though  ...

Candidates for non-rectangular constrained Willmore minimizers [article]

Lynn Heller, Cheikh Birahim Ndiaye
