Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling

Terra Nova, EarlyView.
ABSTRACT Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O‐εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked over time. We apply statistical analyses to a global compilation that apparently resolves shifts in zircon U–Pb, δ18O, and Lu‐Hf data spanning the ...

QK Spaces on the Unit Circle

Journal of Function Spaces, 2014
We introduce a new space QK(∂D) of Lebesgue measurable functions on the unit circle connecting closely with the Sobolev space. We obtain a necessary and sufficient condition on K such that QK(∂D)=BMO(∂D), as well as a general criterion on weight ...

Optimal Regularity Properties of the Generalized Sobolev Spaces

Journal of Function Spaces and Applications, 2013
We prove optimal embeddings of the generalized Sobolev spaces , where is a rearrangement invariant function space, into the generalized Hölder-Zygmund space generated by a function space .

Hyponormal Toeplitz Operators on the Dirichlet Spaces

Abstract and Applied Analysis, 2013
We completely characterize the hyponormality of bounded Toeplitz operators with Sobolev symbols on the Dirichlet space and the harmonic Dirichlet space.

Sharp affine weighted L 2 Sobolev inequalities on the upper half space

Advanced Nonlinear Studies
We establish some sharp affine weighted L 2 Sobolev inequalities on the upper half space, which involves a divergent operator with degeneracy on the boundary.

On global existence and blow up of weak solutions for a wave equation with mixed local and nonlocal propagation

AIMS Mathematics
In this paper, we investigate the initial boundary value problem of a wave equation with mixed local and nonlocal propagation. First, we introduce the spatial framework to study the wave equation, which is the intersection of a classical Sobolev space ...
