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。

2016年3月28日 · BMO-1 / LMS-1 Firebug. Domestic armed forces are armed with a completely unique weapon - rocket infantry flame throwers, which perfectly showed itself in many armed conflicts and wars.

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 ...

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.

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.
