Effective zero-dimensionality for computable metric spaces [PDF]

open access: yes, 2015
We begin to study classical dimension theory from the computable analysis (TTE) point of view. For computable metric spaces, several effectivisations of zero-dimensionality are shown to be equivalent.

Computational differential topology

open access: yesApplied General Topology, 2007
Some of the more differential aspects of the nascent field of computational topology are introduced and treated in considerable depth. Relevant categories based upon stratified geometric objects are proposed, and fundamental problems are identified and ...

Conway games, algebraically and coalgebraically [PDF]

open access: yesLogical Methods in Computer Science, 2011
Using coalgebraic methods, we extend Conway's theory of games to possibly non-terminating, i.e. non-wellfounded games (hypergames). We take the view that a play which goes on forever is a draw, and hence rather than focussing on winning strategies, we ...

Fundamental Results of Cyclic Codes over Octonion Integers and Their Decoding Algorithm

open access: yesComputation, 2022
Coding theory is the study of the properties of codes and their respective fitness for specific applications. Codes are used for data compression, cryptography, error detection, error correction, data transmission, and data storage.

Practice-oriented controversies and borrowed epistemic credibility in current evolutionary biology: phylogeography as a case study [PDF]

open access: yes, 2013
Although there is increasing recognition that theory and practice in science are intimately intertwined, philosophy of science perspectives on scientific controversies have been historically focused on theory rather than practice.

On computing the determinant, other characteristic polynomial coefficients, and inverse in Clifford algebras of arbitrary dimension

open access: yes, 2021
In this paper, we solve the problem of computing the inverse in Clifford algebras of arbitrary dimension. We present basis-free formulas of different types (explicit and recursive) for the determinant, other characteristic polynomial coefficients ...

On the strength of proof-irrelevant type theories

open access: yes, 2008
We present a type theory with some proof-irrelevance built into the conversion rule. We argue that this feature is useful when type theory is used as the logical formalism underlying a theorem prover.

An Algorithmic Argument for Nonadaptive Query Complexity Lower Bounds on Advised Quantum Computation

open access: yes, 2003
This paper employs a powerful argument, called an algorithmic argument, to prove lower bounds of the quantum query complexity of a multiple-block ordered search problem in which, given a block number i, we are to find a location of a target keyword in an

Canonized Rewriting and Ground AC Completion Modulo Shostak Theories : Design and Implementation [PDF]

open access: yes, 2011
AC-completion efficiently handles equality modulo associative and commutative function symbols. When the input is ground, the procedure terminates and provides a decision algorithm for the word problem.
