Now back in print!For centuries, Dalemark has been a land divided by the warring earldoms of the North and South. Now, with the help of the mysterious gods of Dalemark, four extraordinary young people must join forces to reunify their beloved home.When twelve-year-old Moril's father is murdered by soldiers, Moril inherits his ancient cwidder - a musical instrument with a mysterious past. As Moril and his siblings embark on a dangerous journey to escape the evil forces around them, he gradually learns how to channel the cwidder's strange and powerful magic. But is it enough to protect those he loves from the looming threat of war?Cart and Cwidder 823.9/14Jones Diana Wynne1934-20111449407Parmenter HuwothAUDIO9910148871303321Cart and Cwidder (The Dalemark Quartet, Book 1)3654353UNINA04418oam 2200505 450 991082677340332120190911112728.01-299-28130-3981-4425-92-3(OCoLC)897557532(MiFhGG)GVRL8QZI(EXLCZ)99256000000009953820130730h20132013 uy 0engurun|---uuuuatxtccrHomological algebra in strongly non-Abelian settings /Marco Grandis, Universita di Genova, ItalySingapore ;Hackensack, NJ World Scientificc2013New Jersey :World Scientific,[2013]�20131 online resource (xi, 343 pages) illustrationsGale eBooksDescription based upon print version of record.981-4425-91-5 Includes bibliographical references (p. 331-336) and index.Contents; Preface; Introduction; 0.1 Categorical settings for homological algebra; 0.2 Semiexact, homological and generalised exact categories; 0.3 Subquotients and homology; 0.4 Satellites; 0.5 Exact centres, expansions, fractions and relations; 0.6 Applications; 0.7 Homological theories and biuniversal models; 0.8 Modularity and additivity; 0.9 A list of examples; 0.10 Terminology and notation; 0.11 Acknowledgements; 1 Semiexact categories; 1.1 Some basic notions; 1.1.1 Lattices; 1.1.2 Distributive and modular lattices; 1.1.3 Galois connections; 1.1.4 Contravariant Galois connections1.1.5 Isomorphisms, monomorphisms and epimorphisms1.1.6 Pointed categories; 1.1.7 Kernels and cokernels; 1.2 Lattices and Galois connections; 1.2.1 Definition; 1.2.2 Monos and epis; 1.2.3 Kernels and cokernels; 1.2.4 The normal factorisation; 1.2.5 Exact connections; 1.2.6 Normal monos and epis; 1.2.7 The semi-additive structure; 1.2.8 Modular connections; 1.3 The main definitions; 1.3.1 Ideals of null morphisms; 1.3.2 Closed ideals; 1.3.3 Semiexact categories; 1.3.4 Remarks; 1.3.5 Kernel duality and short exact sequences; 1.3.6 Homological and generalised exact categories; 1.3.7 Subcategories1.4 Structural examples 1.4.1 Lattices and connections; 1.4.2 A basic homological category; 1.4.3 A p-exact category; 1.4.4 Graded objects; 1.4.5 The canonical enriched structure; 1.4.6 Proposition; 1.5 Semi-exact categories and normal subobjects; 1.5.1 Semi-exact categories and local smallness; 1.5.2 Exact sequences; 1.5.3 Lemma (Annihilation properties); 1.5.4 Theorem (Two criteria for semi-exact categories); 1.5.5 Normal factorisations and exact morphisms; 1.5.6 Direct and inverse images; 1.5.7 Lemma (Meets and detection properties); 1.5.8 Theorem and Definition (The transfer functor)1.5.9 Remarks 1.6 Other examples of semi-exact and homological categories; 1.6.1 Groups, rings and groupoids; 1.6.2 Abelian monoids, semimodules, preordered abelian groups; 1.6.3 Topological vector spaces; 1.6.4 Pointed sets and spaces; 1.6.5 Categories of partial mappings; 1.6.6 General modules; 1.6.7 Categories of pairs; 1.6.8 Groups as pairs; 1.6.9 Two examples; 1.7 Exact functors; 1.7.0 Basic definitions; 1.7.1 Exact functors and normal subobjects; 1.7.2 Conservative exact functors; 1.7.3 Proposition and Definition (Semiexact subcategories); 1.7.4 Examples2.2.3 Definition and Proposition (Exact ideals)We propose here a study of 'semiexact' and 'homological' categories as a basis for a generalised homological algebra. Our aim is to extend the homological notions to deeply non-abelian situations, where satellites and spectral sequences can still be studied.This is a sequel of a book on 'Homological Algebra, The interplay of homology with distributive lattices and orthodox semigroups', published by the same Editor, but can be read independently of the latter.The previous book develops homological algebra in p-exact categories, i.e. exact categories in the sense of Puppe and Mitchell - a moderaAlgebra, HomologicalHomology theoryAlgebra, Homological.Homology theory.512.64Grandis Marco536821MiFhGGMiFhGGBOOK9910826773403321Homological algebra3933564UNINA
