Connection Form

The connection form arises when applying the exterior connection to a particular frame e. Upon applying the exterior connection to the eα, it is the unique k × k matrixαβ) of one-forms on M such that

In terms of the connection form, the exterior connection of any section of E can now be expressed, for suppose that ξ = Σα eαξα. Then

Taking components on both sides,

where it is understood that d and ω refer to the exterior derivative and a matrix of 1-forms, respectively, acting on the components of ξ. Conversely, a matrix of 1-forms ω is a priori sufficient to completely determine the connection locally on the open set over which the basis of sections e is defined.

Famous quotes containing the words form and/or connection:

    It may be said that the elegant Swann’s simplicity was but another, more refined form of vanity and that, like other Israelites, my parents’ old friend could present, one by one, the succession of states through which had passed his race, from the most naive snobbishness to the worst coarseness to the finest politeness.
    Marcel Proust (1871–1922)

    What is the vanity of the vainest man compared with the vanity which the most modest person possesses when, in connection with nature and the world, he experiences himself as “man”!
    Friedrich Nietzsche (1844–1900)
