The participants in this meeting are almost all carrying out the hard work of making many different types of AGN surveys. Since it’s so much easier to criticize other people’s work than to do actual work myself, I’ll just present some demurs regarding recent papers drawing conclusions from various AGN survey data. In particular I’ll mention some questionable interpretations of surveys of Seyfer...

We study a framework, RLF, for deening natural deduction presentations of linear and other relevant logics. RLF consists in a language together, in a manner similar to that of LF, with a representation mechanism. The language of RLF, the-calculus, is a system of rst-order linear dependent function types which uses a function to describe the degree of sharing of variables between functions and t...

We present a proof of the conjecture NP = PSPACE by showing that arbitrary tautologies of Johansson’s minimal propositional logic admit “small” polynomial-size dag-like natural deductions in Prawitz’s system for minimal propositional logic. These “small” deductions arise from standard “large” tree-like inputs by horizontal dag-like compression that is obtained by merging distinct nodes labeled ...

We analyze Pareto-efficient tax deduction rules for work-related expenses. Pareto efficiency dictates a strict rule marginal deductions along the income distribution. An immediate implication is recipe designing Pareto-improving reforms. apply our theory and simulate reform that introduces non-care household services (housekeeping, gardening, laundry) in United States. The combines rates betwee...
