Galois theory for semiclones [PDF]
, 2015 We present a Galois theory connecting finitary operations with pairs of finitary relations one of which is contained in the other. The Galois closed sets on both sides are characterised as locally closed subuniverses of the full iterative function ...

Provenance for Aggregate Queries [PDF]
, 2011 We study in this paper provenance information for queries with aggregation. Provenance information was studied in the context of various query languages that do not allow for aggregation, and recent work has suggested to capture provenance by annotating ...

Young people's occupational aspirations beyond the aspiration discourse: A sociocultural perspective
British Educational Research Journal, EarlyView.Abstract Young people's aspirations have been the focus of many educational, sociological and psychological studies. This paper argues, firstly, that the concept of aspirations holds greater generative potential than suggested by the policy‐oriented ‘aspiration discourse’.

On orthogonal projections related to representations of the Hecke algebra on a tensor space
Journal of Mathematical Physics, 2022 We consider the problem of finding orthogonal projections P of a rank r that gives rise to representations of the Hecke algebra HN(q) in which the generators of the algebra act locally on the Nth tensor power of the space Cn. It is shown that such projections are global minima of a certain functional.

The Curriculum Journal, EarlyView.Abstract This study explored how lecturers in a post‐92 UK university conceptualise and enact decolonial curriculum principles within their teaching and programme design. Drawing on semi‐structured interviews with academic staff across multiple disciplines, the research adopts a qualitative, phenomenologically informed approach to examine the interplay

Heuristic and Cost-based Optimization for Diverse Provenance Tasks
, 2018 A well-established technique for capturing database provenance as annotations on data is to instrument queries to propagate such annotations. However, even sophisticated query optimizers often fail to produce efficient execution plans for instrumented ...

Algebraic Properties of Valued Constraint Satisfaction Problem [PDF]
, 2015 The paper presents an algebraic framework for optimization problems expressible as Valued Constraint Satisfaction Problems. Our results generalize the algebraic framework for the decision version (CSPs) provided by Bulatov et al. [SICOMP 2005].

Attribute Implication Bases From Galois Connection Structures
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Modeling knowledge systems by determining relationships among key variables have been and currently is a fundamental and nontrivial challenge in real‐world scenarios. Many approaches have been developed to reach this goal, but many of them are heuristic and require of alternative procedures to provide robust and tractable rules.

Algebraic structures of quantum projective field theory related to fusion and braiding. Hidden additive weight [PDF]
Journal of Mathematical Physics, 1994 The interaction of various algebraic structures describing fusion, braiding, and group symmetries in quantum projective field theory is the object of investigation in this article. Structures of projective Zamolodchikov algebras, their representations, spherical correlation functions, correlation characters and enveloping quantum projective field ...
