Dear ?categories? readers, This is to draw your attention to the recently published book ?MONOIDAL TOPOLOGY -- A Categorical Approach to Order, Metric , and Topology?, edited by Dirk Hofmann, Gavin J. Seal and Walter Tholen. It appeared in the ?Encyclopedia of Mathematics and Its Applications? series of Cambridge University Press, as vol. 153; see www.cambridge.org/9781107063945 This 500-page book gives a rather self-contained introduction to the subjects mentioned in its title, including category theory itself. The list of contents below (including chapter authors and lengths of chapters) may describe best to you what to expect. Largely absent is a treatment of (Cauchy-Lawvere-type) completeness which, together with other more advanced themes, is to be treated in a follow-up book. Regards, Walter I Introduction (Robert Lowen, Walter Tholen; 14pp) 1 The ubiquity of monoids and their actions 2 Spaces as categories, and categories of spaces 3 Chapter highlights and dependencies II Monoidal structures (Gavin J. Seal, Walter Tholen; 127pp) 1 Ordered sets 2 Categories and adjunctions 3 Monads 4 Monoidal and ordered categories 5 Factorizations, fibrations, and topological functors III Lax algebras (Dirk Hofmann, Gavin J. Seal, Walter Tholen; 139pp) 1 Basic concepts 2 Fundamental examples 3 Categories of lax algebras 4 Embedding lax algebras into a quasitopos 5 Representable lax algebras IV Kleisli monoids (Dirk Hofmann, Robert Lowen, Rory Lucyshyn-Wright, Gavin J. Seal; 91pp) 1 Kleisli monoids and lax algebras 2 Lax extensions of monads 3 Lax algebras as Kleisli monoids 4 Injective lax algebras as Eilenberg-Moore algebras 5 Domains as lax algebras and Kleisli monoids V Lax algebras as spaces (Maria Manuel Clementino, Eva Colebunders, Walter Tholen; 92pp) 1 Hausdorff separation and compactness 2 Low separation, regularity, and normality 3 Proper and open maps 4 Topologies on a category 5 Connectedness [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
