Formal Objects in Type Theory Using Very Dependent Types

by Jason J. Hickey - In Foundations of Object Oriented Languages 3 , 1996
"... In this paper we present an extension to basic type theory to allow a uniform construction of abstract data types (ADTs) having many of the properties of objects, including abstraction, subtyping, and inheritance. The extension relies on allowing type dependencies for function types to range over ..."

A framework for studying the neurobiology of value-based decision making.

by Antonio Rangel , Colin Camerer , P Read , Montague - Nat. Rev. Neurosci. , 2008
"... Value-based decision making is pervasive in nature. It occurs whenever an animal makes a choice from several alternatives on the basis of a subjective value that it places on them. Examples include basic animal behaviours, such as bee foraging, and complicated human decisions, such as trading in th ..."

in the stock market. Neuroeconomics is a relatively new discipline that studies the computations that the brain carries out in order to make value-based decisions, as well as the neural implementation of those computations. It seeks to build a biologically sound theory of how humans make decisions that can

Impact: towards a framework for understanding the ecological effects of invaders.Biological

by I M Parker , D Simberloff , W M Lonsdale , K Goodell , M Wonham , P M Kareiva , M H Williamson , B Von Holle , P B Moyle , J E Byers , L Goldwasser - Invasions, , 1999
"... Abstract Although ecologists commonly talk about the impacts of nonindigenous species, little formal attention has been given to defining what we mean by impact, or connecting ecological theory with particular measures of impact. The resulting lack of generalizations regarding invasion impacts is m ..."

Formalizing Abstract Algebra in Type Theory with Dependent Records

by Xin Yu, Aleksey Nogin, Alexei Kopylov, Jason Hickey - Universitat Freiburg , 2003
"... algebra suitable for a general reasoning. One of the most common ways to formalize abstract algebra is to make use of a module system to specify an algebra as a theory. However, this approach suffers from the fact that modules are usually not first-class objects in the formal system. In this paper, ..."
Abstract - Cited by 5 (1 self) - Add to MetaCart
, we develop a new approach based on the use of dependent record types. In our account, all algebraic structures are first-class objects, with the natural subtyping properties due to record extension (for example, a group is a subtype of a monoid). Our formalization cleanly separates the axiomatization

Formalizing categorical models of type theory in type theory

by Alexandre Buisse, Peter Dybjer - In International Workshop on Logical Frameworks and Meta-Languages: Theory and Practice , 2007
"... This note is about work in progress on the topic of “internal type theory ” where we investigate the internal formalization of the categorical metatheory of constructive type theory in (an extension of) itself. The basic notion is that of a category with families, a categorical notion of model of de ..."

of dependent type theory. We discuss how to formalize the notion of category with families inside type theory and how to build initial categories with families. Initial categories with families will be term models which play the role of canonical syntax for dependent type theory. We also discuss

E(8) Gauge Theory and a Derivation of K-theory from M-theory

by Duiliu-emanuel Diaconescu, Gregory Moore, Edward Witten
"... The partition function of Ramond-Ramond p-form fields in Type IIA supergravity on a tenmanifold X contains subtle phase factors that are associated with T-duality, self-duality, and the relation of the RR fields to K-theory. The analogous partition function of M-theory on X × S 1 contains subtle pha ..."

phases that are similarly associated with E8 gauge theory. We analyze the detailed phase factors on the two sides and show that they agree, thereby testing M-theory/Type IIA duality as well as the K-theory formalism in an interesting way. We also show that certain D-brane states wrapped on nontrivial

Materials for an exploratory theory of the network society.

"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Typing Algorithm in Type Theory with Inheritance

by Amokrane Saïbi - Proc of POPL'97 , 1997
"... We propose and study a new typing algorithm for dependent type theory. This new algorithm typechecks more terms by using inheritance between classes. This inheritance mechanism turns out to be powerful: it supports multiple inheritance, classes with parameters and uses new abstract classes FUNCLASS ..."
