Complex Vector Lattices: Tensor Products And Multilinear Maps
… functional completions lead to a vector lattice complexification of any Archimedean real vector lattice. Unlike the vector space complexification of an Archimedean real vector lattice, the vector lattice complexification always results in an Archimedean complex vector lattice. For example, we …

Tensor Products Of Vector Seminormed Spaces
… for normed spaces. Moreover, a theory of the complexification of a vector seminormed space is developed in analogy with the theory of complexification of a Banach lattice, and a class of vector seminorms, called admissible vector seminorms, is defined and shown to be equivalent to the class of …

Octonions and the Exceptional Lie Algebra g_2
… of derivations on the octonions and show the complexification is simple. This suffices to show the complexification of the algebra of derivations is isomorphic to g_2 since g_2 is the only semisimple complex Lie algebra of dimension fourteen. Finally, we conclude the algebra of derivations on …

Complex-Analytic Methods in Reconstructive Integral Geometry
… This is done by explicitly looking at the complexification and appealing to the logarithmic Poisson-Jensen formula as well as some results on quasi-conformal mapping theory. These results are used in establishing a stability estimate on a natural generalization of this polynomial space in …

Twistor Space and Celestial Holography
… for H$^3_\mathbb{C}$ and H$^5_\mathbb{C}$, the complexification of 3 and 5 dimensional hyperbolic space. We discuss the minitwistor space of the bulk and its relation to the ambitwistor space of the boundary. The third part of my thesis is a paper on spectral flow and localisation in AdS$_3$ …

Broadcasting regulation and the public-private dichotomy

Beyond orthogonal calculus: the unitary and real cases
… conjugation of the matrices.<br/><br/>From the complexification-realification adjunction between real and complex vector spaces we construct functors between the orthogonal and unitary calculi, allowing for movement between these two versions of calculus, and direct comparisons of the Taylor …

Hamiltonian Actions In Integral Kahler And Generalized Complex Geometry
… integral Kahler manifold preserved by the complexification a of the Hamiltonian group action. Guillemin and Sjamaar generalized this result to irreducible subvarieties preserved only by a Borel subgroup. In another direction, O'Shea and Sjamaar proved a convexity result for the moment map …

Modelling evolution of genome size in prokaryotes in response to changes in their abiotic environment
… gyre regions of the ocean) and genome complexification in variable environments. Horizontal gene transfer (HGT) was also introduced, but was found to act in a similar manner as gene duplication and shown no important contribution to the speed of evolution and the adaptive potential of …

Compact Symmetric Spaces, Triangular Factorization, and Cayley Coordinates
… point set of an involution θ of U. Let G be the complexification of U. We consider the intersections of the image of the Cartan embedding Φ : U/K → U ⊂ G : uK → uu⁻ᶿ with the strata of the Birkhoff (or triangular, or LDU) decomposition G = ⫫(w∈W) ∑(G/w), ∑(G/w) = N⁻wHN⁺ relative to a θ-stable …

A complex transdisciplinary exploration of South African climate mitigation policy

Theoretical and experimental studies of the dynamics and acoustics of forced ordered granular networks
… The pure breather is asymptotically studied by a complexification/averaging technique, showing nearly complete but reversible energy exchanges between the excited and absorbing chains as the breather propagates to the far field. We analytically prove that the reason for this dynamic overshoot …

Holomorphic Extensions in the Structure R_{an,exp}
In this thesis we consider real analytic functions, i.e. functions which can be described locally as convergent power series and ask the following: Which real analytic functions definable in R_{an,exp} have a holomorphic extension which is again definable in R_{an,exp}? Finding a holomorphic …

Intercorporeality and Technology: toward a new cognitive, aesthetic and communicative paradigm in the performing arts
