SURREAL ORDERED EXPONENTIAL FIELDS [PDF]
The Journal of Symbolic Logic, 2021 Abstract In 2001, the algebraico-tree-theoretic simplicity hierarchical structure of J. H. Conway’s ordered field ${\mathbf {No}}$ of surreal numbers was ...

Annealing of skyrmion lattice in van der Waals magnet via field modulation [PDF]
Nature CommunicationsIn atomic solids, annealing transforms disordered structures into ordered crystals through thermal activation, whereas realizing a comparable process in quasiparticle lattices is highly desirable. Magnetic skyrmions are topological spin textures that can

A nullstellensatz and a positivstellensatz for ordered differential fields [PDF]
Mathematical Logic Quarterly, 2013 AbstractWe use the model completeness and axiomatisation of the theory of closed ordered differential fields to give a differential version of Dubois, Krivine and Risler's nullstellensatz and Stengle's positivstellensatz for ordered fields.

Some Results on Single Valued Neutrosophic Bi-ideals in Ordered Semigroups [PDF]
Neutrosophic Sets and Systems, 2021 The importance of the theory of neutrosophy is due to its connections with several fields of sciences, engineering, and technology. So, the aim of this paper is to relate neutrosophy with some algebraic structures mainly the ordered semigroups.

Uniformly continuous 1-1 functions on ordered fields not mapping interior to interior [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2008 In an earlier work we showed that for ordered fields F not isomorphic to the reals R, there are continuous 1-1 unctions on [0, 1]F which map some interior point to a boundary point of the image (and so are not open).

European Physical Journal C: Particles and Fields, 2021 In a soliton sector of a quantum field theory, it is often convenient to expand the quantum fields in terms of normal modes. Normal mode creation and annihilation operators can be normal ordered, and their normal ordered products have vanishing ...

The fabulous destiny of Richard Dedekind
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2021 By using the preliminary results given in a previous divulgative note, we present here a concise and self--contained introduction to the construction of the real field as the unique, up to increasing isomorphism, Dedekind complete totally ordered field ...
