Alexey Cheskidov, Susan Friedlander, Natasa Pavlović

摘要:

讨论了一类非线性耦合常微分方程无穷大组的性质。该系统模拟了无粘流体运动方程中的一些性质,如二次非线性的斜对称性和三维尺度。证明了具有强迫的系统存在唯一的平衡点,且每个解在有限时间内以$H^{5/6}$ -范数爆破。Onsager的猜想被证实的模型系统。

英文摘要:

Properties of an infinite system of nonlinearly coupled ordinary differential equations are discussed. This system models some properties present in the equations of motion for an inviscid fluid such as the skew symmetry and the 3-dimensional scaling of the quadratic nonlinearity. It is proved that the system with forcing has a unique equilibrium and that every solution blows up in finite time in $H^{5/6}$-norm. Onsager's conjecture is confirmed for the model system.
