In harmonic analysis in mathematics, a function of bounded mean oscillation, also known as a BMO function, is a real-valued function whose mean oscillation is bounded (finite).

2017年10月9日 · bmo-1喷火战车里面有32具rpo-a火箭筒，分给7个喷火步兵，可以每人4具多。 如果使用得法，就可以摧毁30个左右的敌人据点。 不过，BMO-1喷火战车究竟有多少意义，就很难说。

2013年1月31日 · British Mathematical Olympiad, Round 1 (BMO 1) This is a 3½-hour paper with 6 problems (the first being intended to be more accessible than the rest), taken by students in their own schools. Selection is based on performance in …

As a follow-on Round to the Senior Mathematical Challenge (SMC), the British Mathematical Olympiad Round 1 (BMO1) is a 3.5 hour Olympiad consisting of six problems requiring full written solutions. As well as challenging high-scorers from the SMC, the British Mathematical Olympiad is an entry point to the training and selection programme for ...

2019年1月10日 · In this paper we investigate the question of the existence of global weak solution for the compressible Navier Stokes equations provided that the initial momentum ρ0u0 belongs to bmo−1(RN) with N = 2, 3 and is radially symmetric.

2021年10月11日 · We can also prove a correspondance between BMO and BMO $^{-1}$ because $f\in$ BMO $^{-1}$ if and only if there exists $g=(g_1,...,g_d)$ with $g_i\in$ BMO for all $i$ such that $f = \nabla\cdot g$. This is all well known in Harmonic Analysis.

2023年12月2日 · 定义： 函数空间 BMO^{-1}\ 定义为 \{f(x) \in \mathcal{S}^{\prime}\left(\mathbb{R}^d\right) \mid \|f\|_{BMO^{-1}}<\infty \},\\ 其中 \begin{aligned} \|f\|_{BMO^{-1}} & := \sup _{x, R>0} \left(|B(x, R)|^{-1} \int_{\left[0, R^2\right] \times B(x, R)}|e^{t\Delta}f|^2 d y d t \right)^{\frac12}. \end{aligned}\\

In the first round (BMO 1), solvers have 3.5 hours to solve 6 problems. High scorers can move on into the second round (BMO 2), where solvers have 3.5 hours to solve 4 problems. For both rounds, each problem is worth 10 points. Like most Olympiads, complete solutions are required in order to get full credit.
