We have the following result: Theorem 34. Let A be a

matrix with A and A"1 in B(l2). Then A has a unique Cholesky decomposition; that

is, A = LLT, where L and L"1 are lower triangular biinfinite matrices in B(/2) with ...

The quantity M measures the rate of production of mechanical turbulence, which

arises when the fluid is stirred; it depends primarily on vertical variations of wind

or. near the ground, on wind speed and roughness. It is almost always

In the upper ionosphere, electrons gyrate at a frequency of ~106/ sec, whereas

**positive**ions have a frequency of only a few thousand gyrations per second. Tobe precise, the drift motion can occur when a charged particle can gyrate many ...
