On the identity type as the type of computational paths

AF Ramos, RJGB De Queiroz… - Logic Journal of the …, 2017 - academic.oup.com
We present a way of formalizing the intensional identity type based on the notion of
computational paths which will be taken to be proofs of propositional equality, and thus …

From Tractatus to Later Writings and Back – New Implications from Wittgenstein's Nachlass

RJGB de Queiroz - SATS, 2023 - degruyter.com
As a celebration of the Tractatus 100th anniversary it might be worth revisiting its relation to
the later writings. From the former to the latter, David Pears recalls that “everyone is aware of …

Towards a homotopy domain theory

DO Martínez-Rivillas, RJGB de Queiroz - Archive for Mathematical Logic, 2023 - Springer
An appropriate framework is put forward for the construction of λ-models with∞-groupoid
structure, which we call homotopic λ-models, through the use of an∞-category with …

Solving homotopy domain equations

DO Martínez-Rivillas, RJGB de Queiroz - arXiv preprint arXiv:2104.01195, 2021 - arxiv.org
In order to get $\lambda $-models with a rich structure of $\infty $-groupoid, which we call"
homotopy $\lambda $-models", a general technique is described for solving domain …

The Theory of an Arbitrary Higher -Model

One takes advantage of some basic properties of every homotopic\(\lambda\)-model (eg
extensional Kan complex) to explore the higher\(\beta\eta\)-conversions, which would …

A topological application of labelled natural deduction

TML Veras, AF Ramos, RJGB de Queiroz… - arXiv preprint arXiv …, 2019 - arxiv.org
We use a labelled deduction system based on the concept of computational paths
(sequences of rewrites) as equalities between two terms of the same type. We also define a …

Explicit computational paths

AF Ramos, RJGB de Queiroz… - arXiv preprint arXiv …, 2016 - arxiv.org
The treatment of equality as a type in type theory gives rise to an interesting type-theoretic
structure known asidentity type'. The idea is that, given terms $ a, b $ of a type $ A $, one …
