Two-dimensional regularity and exactness
Article history: Received 19 April 2013 Received in revised form 7 August 2013 Available online 25 November 2013 Communicated by J. Adámek MSC: 18F10; 18A32; 18D05 We define notions of regularity and (Barr-)exactness for 2-categories. In fact, we define three notions of regularity and exactness, each based on one of the three canonical ways of factorising a functor in Cat: as (surjective on obj...
متن کاملTwo-dimensional Datapath Regularity Extraction
This paper presents a new method to automatically extract regular structures from logic netlists containing datapath circuitry. The goal of datapath extraction is the exploitation of structural regularity to efficiently obtain regular placements which are typically more compact. Datapaths constitute increasingly sizeable parts of ever more and larger circuits, hence flexible technology-independ...
متن کاملQuasivarieties and varieties of ordered algebras: regularity and exactness
We characterise quasivarieties and varieties of ordered algebras categorically in terms of regularity, exactness and the existence of a suitable generator. The notions of regularity and exactness need to be understood in the sense of category theory enriched over posets. We also prove that finitary varieties of ordered algebras are cocompletions of their theories under sifted colimits (again, i...
متن کاملGlobal Regularity of Two-dimensional Flocking Hydrodynamics
We study the systems of Euler equations which arise from agent-based dynamics driven by velocity alignment. It is known that smooth solutions of such systems must flock, namely — the large time behavior of the velocity field approaches a limiting “flocking” velocity. To address the question of global regularity, we derive sharp critical thresholds in the phase space of initial configuration whi...
متن کاملAnisotropic Analysis of Regularity in a Two-dimensional Gaussian Model
Although the classical Fractional Brownian Motion is often used to describe porosity, it is not adapted to anisotropic situations. In the present work, we introduce anisotropic Gaussian elds with stationary increments and asymp-totic self-similarity properties. They are good candidates to modelize homogeneous anisotropic images, like osteoporosis radiographs. Unfortunately, the paths of all Gau...
