sigma's Usage Examples:

(sources), σ s 2 {\displaystyle \sigma _{s}^{2}} is the power of the interferer, and σ n 2 {\displaystyle \sigma _{n}^{2}} is the noise power, and † {\displaystyle.

It can be proved, using the reasonings above, that "sigma; is a permutation of the integers and that the permuted series converges to the given real number"nbsp;M.

Formally, a circular shift is a permutation σ of the n entries in the tuple such that either\sigma(i)\equiv (i+1) modulo n, for all entries i 1, .

{\displaystyle {\begin{aligned}\nu _{0}""\nu _{0}+n\\\nu _{0}"{\sigma _{0}^{2}}""\nu _{0}\sigma _{0}^{2}+\sum _{i1}^{n}(x_{i}-\mu )^{2}\end{aligned}}} or equivalently.

Note that for all i \in I we can define the maps \varphi_i : G \rightarrow G_i by \sigma \mapsto \sigma_{|L_i}.

For example, in a 2-D Hilbert space with 3 measurements \sigma_x, \sigma_y, \sigma_z, each measurement has 2 outcomes, each of which has a projector Ei, for 6 projectors, whereas the real dimension of the space of density matrices is (2⋅22)/24, leaving A to be 6 x 4.

And the rearranged series, \textstyle \sum_{i1}^\infty a_{\sigma(i)}, then diverges to \infty.

_{\nu }B_{\nu }(T)d\nu \over \int _{0}^{\infty }B_{\nu }(T)d\nu }{\Big (}{\pi \over \sigma T^{4}}{\Big )}\int _{0}^{\infty }\kappa _{\nu }B_{\nu }(T)d\nu.

\mathrm {Ha} BL{\sqrt {\frac {\sigma }{\mu }}}} where B is the magnetic field intensity L is the characteristic length scale σ is the electrical conductivity.

\left(\epsilon ^{0123}\eta ^{0\mu }\eta ^{1\nu }\eta ^{2\rho }\eta ^{3\sigma }\epsilon _{\mu \nu \rho \sigma }\eta ^{00}\eta ^{11}\eta ^{22}\eta ^{33}\epsilon.

A popular choice of gauge is the so-called De Donder gauge, also known as the [coordinate condition|harmonic] condition or harmonic gaugeg^{\mu\nu} \Gamma^{\sigma}_{\mu\nu} 0 \,.

A rule-of-thumb bandwidth estimatorIf Gaussian basis functions are used to approximate univariate data, and the underlying density being estimated is Gaussian, the optimal choice for h (that is, the bandwidth that minimises the mean integrated squared error) is:h \left(\frac{4\hat{\sigma}^5}{3n}\right)^{\frac{1}{5}} \approx 1.
