The fusion of algebra, research and geometry, and their software to actual global difficulties, were dominant topics underlying arithmetic for over a century. Geometric algebras, brought and labeled through Clifford within the past due nineteenth century, have performed a trendy function during this attempt, as visible within the mathematical paintings of Cartan, Brauer, Weyl, Chevelley, Atiyah, and Bott, and in functions to physics within the paintings of Pauli, Dirac and others.

The homogeneous dimension doublecounts the dimension of the “missing directions”. The Cayley transform is the map σ : N → S, given by σ(x, t) = 1+ |x|2 4 2 −1 + |z|2 1+ |x|4 |x|4 − z x, −1 + + |z|2 + 2z 4 16 for all (x, t) in N . It is a (nontrivial) exercise in calculus to show that σ is Carnot–Carath´eodory conformal when N is given the left-invariant Carnot– Carath´eodory structure which at the group identity (0, 0) is Fn (that is, {(x, 0) : x ∈ Fn }) with its standard inner product. The Jacobian of the transformation is given by the Qth power of the dilation factor, that is, Jσ (x, t) = 1+ |x|2 4 2 −Q/2 + |z|2 .

The group GL(n, Qp ) is not semisimple, and this is not quite the analogue of a Riemannian symmetric space. One example of a discrete symmetric space may be obtained by restricting attention to the space L1 of lattices whose volume is equal to that of the standard lattice. It follows from the invariant factor theorem that L1 may be identified with the coset space SL(n, Qp )/SL(n, Op ). The more standard example of a discrete symmetric space is a quotient space of L. Define an equivalence relation ∼ on L by the stipulation that L1 ∼ L2 if L1 = λL2 for some λ in Qp ; the equivalence class of L is written [L].
