WebMar 8, 2016 · So the function that picks out the i'th coordinate of a vector with respect to a basis is a covector. The dual space to the space of covectors is also a vector space. One might call it the space of covectors of covectors. If one writes a covector as then the 's are a basis for the space of covectors of covectors. WebJun 6, 2024 · Here $ \cdot $ is the standard norm of an $ r $- vector and $ \omega \cdot \alpha $ is the scalar product of a vector and a covector. The mass $ \alpha _ {0} $ and the co-mass $ \omega _ {0} $ are adjoint norms in the spaces of $ r $- vectors $ V _ {[} r] $ and $ r $- covectors $ V ^ {[} r] $, respectively. structural durability \u0026 health monitoring期刊

In physics, especially in multilinear algebra and tensor analysis, covariance and contravariance describe how the quantitative description of certain geometric or physical entities changes with a change of basis. In modern mathematical notation, the role is sometimes swapped. In physics, a basis is sometimes thought of as a set of reference axes.
