Aspects of Generalized Geometry: Branes with Boundary, Blow-ups, Brackets and Bundles
This thesis explores aspects of generalized geometry, a geometric framework introduced by Hitchin and Gualtieri in the early 2000s. In the first part, we introduce a new class of submanifolds in stable generalized complex manifolds, so-called Lagrangian branes with boundary. We establish a …

Centrifugal compressor return channel shape optimization using adjoint method
… A proper objective function definition and a generalized geometry parametrization and manipulation algorithm were developed, and the appropriate adjoint equations and boundary conditions were derived for internal flow of an axisymmetric incompressible laminar flow. The adjoint-based gradient …

Curvatures in generalized Kähler geometry
Bi-Hermitian is an extension of Kähler geometry which arose first in the study of supersymmetricσ-models in the 1980s. It was later rediscovered by Gualtieri, within Hitchin’s generalized geometry program, and rechristened as generalized Kähler geometry. In this thesis, we study a wide variety of …

Lie Theory in Generalized Kähler Geometry
Generalized Kähler (GK) geometry was discovered in the study of N = (2, 2) supersymmetric σ-models. In this thesis we develop a new approach to GK geometry by addressing the integration problem of GK structures. To tackle this problem, we first reformulate the definition of GK structures in terms …
