The tangent space at x∈Ω is the vector space (10.31)TxE=(x,u)∣u∈Ewith the operations (10.32)(x,u)+(x,v)=(x,u+v)andα(x,u)=(x,αu) (ii) The tangent bundle TE of Ω⊂E is the collection of all tangent space, i.e., (10.33)TE=⋃x∈ΩTxE One thinks of (x,...
doi:10.1007/978-3-642-84439-3_2At every point p of a differentiable manifold M, one can introduce a linear space, called the tangent space T P( M). A tensor field is a (smooth) map which assigns to each point p ∈ Ma tensor of a...Straumann, Norbert...

A standard concept in physics and engineering is that of a force field. The gravitational force field of the earth, for example, assigns to each point of space a force (vector) directed at the center of the earth. 2.3 Definition A vector field V on R3 is a function that assigns to eac...
