The prior 20 years have witnessed a revolution within the earth sciences. The quantitative, instrument-based measurements and actual versions of. geophysics, including advances in expertise, have notably reworked the best way the Earth, and particularly its crust, is defined. The research of the magnetism of the rocks of the Earth's crust has performed an enormous half during this transformation.

If α is an isomorphism, it is easy to check that if U is a subspace of V and α(U ) = S ⊂ W , then α∗ (S ◦ ) = U ◦ . Although there is not a natural isomorphism between V and V ∗ , if we dualize again and consider V ∗∗ = (V ∗ )∗ , then in fact there is a natural map S : V → V ∗∗ given by S(v)(φ) = φ(v). It is immediate that S is linear, and moreover it is injective. Hence if V is finite dimensional, S is an isomorphism. e. a hyperplane in V ∗ . Similarly, given a point p ∈ P(V ∗ ), its annihilator in V ∗∗ ∼ = V is a hyperplane in V , thus we see that the set of hyperplanes in V can naturally be identified with a projective space.

When we remove the poles, the range of values for θ and φ are 0 ≤ θ < 2π, 0 < φ < π, and the antipodal map corresponds to the map (θ, φ) → (θ + π, π − φ). (where the first component must be read modulo 2π). But then we may identify the space of lines in R2 with pairs (θ, φ) ∈ [0, π] × (0, π) where we identify (0, φ) with (π, π − φ). Drawing a picture of a square with the appropriate identifications, we immediately see that this space is a Mobius band. THE CLASSICAL GROUPS 33 7. T HE GENERAL LINEAR GROUP Recall that given a vector space V over a field k the group GL(V ) is the set of invertible linear transformations of V .

Our goal, of course, is to show that in fact this group is all of Sp(V ). 3. The group T acts transitively on V − {0}. Indeed T acts transitively on the set of hyperbolic pairs. Proof. Suppose that v, w ∈ V . If B(v, w) = 0, then set u = w − v and a = B(v, w)−1 so that τu,a (v) = v + aB(v, u)u = v + B(v, w)−1 B(v, w)(w − v) = w. If B(v, w) = 0, then we may find φ ∈ V ∗ such that φ(v) and φ(w) = 0. Then setting −1 u = RB (φ) we have B(v, u) = 0 and B(v, w) = 0. Then by what has already been established, there are symplectic transvections τ1 , τ2 taking v to u and w to u respectively.
