Twisted Morava K-theory, along with computational techniques, including a universal coefficient theorem and an Atiyah-Hirzebruch spectral sequence, was introduced by Craig Westerland the first author. We employ these techniques to compute twisted K-theory of all connective covers stable orthogonal group unitary group, their classifying spaces, as well spheres Eilenberg-MacLane spaces. This exte...

We derive maximal regularity properties of these operators in UMD-valued Sobolev spaces. Our main aim is to prove existence...

This book is a retrospective on universal logic in the 20th century. It gathers papers and book extracts in the spirit of universal logic from 1922 to 1996. Each of the 15 items is presented by a specialist explaining its origin, import and impact, supported by a bibliography of correlated works. Some of the pieces presented here, such as “Remarques sur les notions fondamentales de la méthodolo...

If G is a Polish group, then the category of Polish G-spaces and continuous G-mappings has a universal object. §0. Preface It is known from [2] that 0.1. Theorem (de Vries). Let G be a separable locally compact metric group. Then the category of continuous G-maps and separable complete metric G-spaces has a universal object. In other words, there is a separable complete metric space X on which ...
