Homotopy algebras via resolutions of operads
Summary: All algebraic objects in this note will be considered over a fixed field of characteristic zero. If not stated otherwise, all operads live in the category of differential graded vector spaces over . For standard terminology concerning operads, algebras over operads, etc., see either the original paper by J. P. May [“The geometry of iterated loop spaces”, Lect. Notes Math. 271 (1972; Zbl 0244.55009)], or an overview [J.-L. Loday, “La renaissance des opérads”, Sémin. Bourbaki 1994/95,...
Homotopy diagrams of algebras
The paper is concerned with homotopy concepts in the category of chain complexes. It is part of the author’s program to translate [J. M. Boardman and R. M. Vogt, Homotopy invariant algebraic structures on topological spaces, Lect. Notes Math. 347, Springer-Verlag (1973; Zbl 0285.55012)] from topology to algebra.In topology the notion of operad extracts the essential algebraic information contained in the following example (endomorphism operad).The endomorphism operad of a based space consists...
Homotopy type of Euclidean configuration spaces
Let denote the configuration space of pairwise-disjoint -tuples of points in . In this short note the author describes a cellular structure for when . From results in [F. R. Cohen, T. J. Lada and J. P. May, The homology of iterated loop spaces, Lect. Notes Math. 533 (1976; Zbl 0334.55009)], the integral (co)homology of is well-understood. This allows an identification of the location of the cells of in a minimal cell decomposition. Somewhat more detail is provided by the main result here,...

I2Geo: a Web-Library of Interactive Geometry
This paper describes I2Geo, the platform of the Intergeo project enabling math educators throughout Europe to publicly share interactive geometry constructions. This cross-cultural web-based platform makes each resource, be it a construction, a scenario of use, or a complete course, referenceable, editable, and reviewable. It is based on reusable tools, a fine grained ontology of mathematical concepts and skills, together with a description of educational pathways in Europe: together they allow...
