Isotropic Landau-Lifshitz Equation
By using the geometric concept of PDEs with prescribed curvature representation, we prove that the 1+2 dimensional isotropic Landau-Lifshitz equation is gauge equivalent to a 1+2 dimensional nonlinear Schrödinger-type system. From the nonlinear Schrödinger-type system, we construct blowing up H3(R2)-solutions to the Landau-Lifshitz equation, which reveals the blow up phenomenon of the equation.
متن کاملEndpoint bounds for the non-isotropic Falconer distance problem associated with lattice-like sets
Let S ⊂ R be contained in the unit ball. Let ∆(S) = {||a− b|| : a, b ∈ S}, the Euclidean distance set of S. Falconer conjectured that the ∆(S) has positive Lebesque measure if the Hausdorff dimension of S is greater than d 2 . He also produced an example, based on the integer lattice, showing that the exponent d 2 cannot be improved. In this paper we prove the Falconer distance conjecture for t...
متن کاملBeyond dyspnoea as an endpoint in acute heart failure trials.
Acute heart failure syndromes (AHFS) has been defined as new onset or recurrence of gradually or rapidly worsening signs and symptoms of heart failure (HF) necessitating urgent or emergency therapeutic intervention. The number of hospitalizations for AHFS continues to increase and they account for 1 million admissions annually in both Europe and the USA. Dyspnoea is the most common presenting s...
متن کاملThermal composition fluctuations near the isotropic Lifshitz critical point in a ternary mixture of a homopolymer blend and diblock copolymer
We have studied thermal composition fluctuations of a ternary symmetric homopolymer/diblock copolymer system of PEE/PDMS/PEE-PDMS @PEE and PDMS being poly~ethyl ethylene! and poly~dimethyl siloxane!, respectively# in its disordered state with small angle neutron scattering for concentration F of diblocks up to 15%. The phase diagram shows three characteristic regimes; ~1! below the Lifshitz con...
متن کاملCosmology of the Lifshitz universe
We study the ultraviolet complete non-relativistic theory recently proposed by Hořava. After introducing a Lifshitz scalar for a general background, we analyze the cosmology of the model in Lorentzian and Euclidean signature. Vacuum solutions are found and it is argued the existence of non-singular bouncing profiles. We find a general qualitative agreement with both the picture of Causal Dynami...
