Intermediate dimensions of products
We construct under the Continuum Hypothesis an example of a compact space no finite power of which contains an infinite closed subset that is of finite dimension greater than 0. This is a partial answer to a question of the third author. © 2006 Elsevier B.V. All rights reserved.
متن کاملGrand Uni cation at Intermediate Mass Scales through Extra Dimensions
One of the drawbacks of conventional grand uni cation scenarios has been that the uni cation scale is too high to permit direct exploration. In this paper, we show that the uni cation scale can be signi cantly lowered (perhaps even to the TeV scale) through the appearance of extra spacetime dimensions. Such extra dimensions are a natural consequence of string theories with largeradius compacti ...
متن کاملGrand Unification at Intermediate Mass Scales through Extra Dimensions
One of the drawbacks of conventional grand unification scenarios has been that the unification scale is too high to permit direct exploration. In this paper, we show that the unification scale can be significantly lowered (perhaps even to the TeV scale) through the appearance of extra spacetime dimensions. Such extra dimensions are a natural consequence of string theories with largeradius compa...
متن کاملDesmoplakin assembly dynamics in four dimensions: multiple phases differentially regulated by intermediate filaments and actin
he intermediate filament (IF)–binding protein desmoplakin (DP) is essential for desmosome function and tissue integrity, but its role in junction assembly is poorly understood. Using time-lapse imaging, we show that cell–cell contact triggers three temporally overlapping phases of DP-GFP dynamics: (1) the de novo appearance of punctate fluorescence at new contact zones after as little as 3 min;...
متن کاملChiral Dynamics in Weak , Intermediate , and Strong Coupling Qed in Two Dimensions
N flavor QED in two dimensions is reduced to a quantum mechanics problem with N degrees of freedom for which the potential is determined by the ground state of the problem itself. The chiral condensate is determined at all values of temperature, fermion masses, and the θ parameter. In the single flavor case, the anomalous mass (m) dependence of the chiral condensate at θ = π at low temperature ...
