Let Gk denote the quotient of the fundamental group G of a link in S 3 by the product of the (k + 2)-nd lower cental series terms of the normal closures of meridians, k > 0. In contrast to a theorem of Waldhausen, we show that Gk is the finest (in certain sense) quotient of G, invariant under k-quasi-isotopy (which is a higher order analogue of link homotopy, studied in [MR1]) and at the same t...
The generic concepts of Archaeoteleia Masner and Proteroscelio Brues are expanded to accommodate two new species that are here described: Archaeoteleia astropulvis Talamas sp. n. and Proteroscelio nexus Talamas sp. n. A specimen of Archaeoteleia from Baltic amber is illustrated and discussed. Diagnoses of Proteroscelio, Proterosceliopsis Ortega-Blanco, McKellar & Engel and Bruescelio Ortega-Bla...

This paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices. A nonparametric analysis of consumer expenditure patterns suggests that Engel curves require quadratic terms in the logarithm of expendit...
