**Crossing Platforms a Macintosh/Windows Phrasebook: A Dictionary for Strangers in a Strange Land**

Like tourists in a overseas land, Mac clients operating in home windows or home windows clients engaged on a Mac usually locate themselves in strange territory without guidebook. Crossing systems: A Macintosh/Windows Phrasebook, with details provided in a translation dictionary-like layout, deals clients a convenient method of translating abilities and data from one platform to the opposite.

S. Then in [11, Sect. 6] we work through the integrable systems framework for the corresponding family of harmonic maps Ψ : R2 → CP2 , showing that they are generically superconformal of ﬁnite type, and determining their harmonic sequences, Toda solutions, algebras of polynomial Killing ﬁelds, and spectral curves. 4 are interesting because they construct large families of superconformal harmonic tori in CP2 . 7. Examples from evolving non-centred quadrics We will now apply the construction of Sect.

J + u j =a+1 αj − u Then u and θ satisfy Q(u)1/2 sin θ ≡ A for some A ∈ R. Suppose that αj +u > 0 for j = 1, . . , a and αj − u > 0 for j = a +1, . . , m−1 and t ∈ (− , ). Deﬁne a subset N of Cm to be x1 eiθ1(t) α1 +u(t), . . , xa eiθa(t) αa +u(t), xa+1 eiθa+1(t) αa+1 −u(t), . . , xm−1 eiθm−1 (t) αm−1 −u(t), xm + 21 u(t)−iAt : 2 2 −· · ·−xm−1 +2xm = 0 . t ∈ (− , ), xj ∈ R, x12 +· · ·+xa2 −xa+1 Then N is a special Lagrangian submanifold in Cm . As in Sect. 3, if we assume that θ (t) ∈ (−π/2, π/2) for t ∈ (− , ) then u is an increasing function of t, and we can choose to regard everything as a function of u rather than of t.
