Higgs moduli and Matsuki correspondence
M.Phil.Given a Riemann surface Σ and a complex reductive group G꜀, a G꜀-Higgs bundle on Σ is a pair (P, φ), where P is a principal G꜀-bundle on Σ, and φ is a section of the vector bundle Ad(P) ⊗ KΣ. In this paper, we study the coarse moduli space Mᴳᶜ of G꜀-Higgs bundle over Σ. Mᴳᶜ has a natural hyperkähler structure coming from hyperkähler reduction of the solution space for the Hitchin system. The Higgs moduli Mᴳᶜ plays an important role in conformal field theory and in geometric Langlands correspondence over C.We study the relations between the Higgs moduli Mᴳᶜ and the Matsuki correspondence for groups. Matsuki correspondence gives a bijection between the set of real forms of G꜀ and the set of symmetric complex subgroups of G꜀, our work is to interpret the Matsuki correspondence as a duality statement for certain BAA branes and BBB branes on Mᴳᶜ.給定一個黎曼面Σ 和一個複約化群G꜀,若P是Σ 上的一個G꜀主叢,而φ為向量叢Ad(P) ⊗ KΣ 的一個截面,我們則稱(P, φ) 為Σ上的一個G꜀ Higgs 叢。我們在本文中探討Σ上G꜀ Higgs 叢的粗略的模空間Mᴳᶜ。Mᴳᶜ 具有自然的來自Hitchin 系統解空間的hyperkähler約化的hyperkähler結構。這個粗略的模空間Mᴳᶜ 在保形場理論和幾何Langlands 綱領中起著重要的作用。我們研究模空間Mᴳᶜ與Matsuki對應的關係。Matsuki給予了G꜀ 的實形式集與對稱複子群集之間的一一對應,我們的工作是將Matsuki對應理解為Mᴳᶜ上的某些BAA膜和BBB膜之間的對偶性質。Chan, Ki Fung.Thesis M.Phil.

Affine Matsuki correspondence for sheaves
We lift the affine Matsuki correspondence between real and symmetric loop
group orbits in affine Grassmannians to an equivalence of derived categories of
sheaves. In analogy with the finite-dimensional setting, our arguments depend
upon the Morse theory of energy functions obtained from symmetrizations of
coadjoint orbits. The additional fusion structures of the affine setting lead
to further equivalences with Schubert constructible derived categories of
sheaves on real affine Grassmannians.Comment: Add a new section (Section 9) on compatibility with Hecke action

Design of pharmaceutical tablet formulation for a low water soluble drug : search for the critical concentration of starch based disintegrant applying percolation theory and F-CAD (Formulation-Computer Aided Design)
The topic of this PhD work is to search the critical concentration of starch based disintegrant applying percolation theory and F-CAD (Formulation-Computer Aided Design) in order to design a pharmaceutical tablet formulation for a low water soluble drug. Critical concentration of maize starch (MS) for a ternary mefenamic acid (MA) tablet formulation with respect to a minimum disintegration time is investigated. Additionally implemented application of F-CAD to compute the disintegration time of MA tablet formulation is presented. This topic is related to push forward the idea of Quality by Design (QbD) of FDA (Food and Drug Administration) / EMEA (European Medicines Agency) / PMDA (Pharmaceuticals and Medical Devices Agency) and the exploration of the design space according to ICH (International Conference of Harmonization) Q8.
The results of this work shows that the application of percolation theory is not limited to binary tablet formulation. The critical concentration of MS described by the renormalized MS concentration, MS/(MS+MA) applying the renormalization technique is always equal 0.198 (dimensionless). Moreover the critical concentration of MS is optimized using the spline approximation with the dataNESIA software. It is leading to a minimum disintegration time at 0.206, dimensionless, renormalized, which is very close to the experimental value of 0.198. According to the percolation theory, a minimum disintegration time corresponds to the formation of a continuous water-conducting cluster through the entire tablet. The critical volume fraction of an ‘infinite cluster’ that water can diffuse through the entire MA tablets are calculated with taking into account for the geometrical considerations between MS and MA particles based on random close packed (RCP) spheres system. The critical volume fraction of MS is calculated by the multiplication of critical concentration of MS and the solid fraction of MA tablets; which is within the range of 0.16 ± 0.01 (v/v). It is concluded that the critical volume fraction for three dimensional lattices is equal to 0.16 ± 0.01 (v/v); which is useful for the calculation of the critical concentration of starch based disintegrant in order to design the pharmaceutical tablet formulation based on scientific approach proposed by ICH Q8 guidance.
In addition, the disintegration behavior in the neighborhood of the percolation threshold is explained mathematically by the basic equation of the percolation theory, yielding a critical exponent q equal to 0.28 ± 0.06 (Quality of fit: r2 = 0.84). This value is close to the critical exponent for three dimensional lattices (q = 0.4). Thus, it is important, within a planned experimental design to optimize the disintegrant to take into account the percolation theory. However it has to be kept in mind that the determination of the percolation threshold and critical exponent does not give an answer about the absolute value of the disintegration time. Dissolution Simulation (DS) module, which is the one of F-CAD based on cellular automata algorithm is used to simulate the disintegration time of a MA tablet. Disintegration time of tablet is assumed as the time elapsed till the water is detected at the geometric center of the virtual tablet. Comparison of experimental disintegration time of MA tablet and computed specific time point for water to reach the geometric center of the tablet by using F-CAD software has been carried out and shown an acceptable correlation (Correlation coefficient: r = 0.81). The detailed evaluation of the data shows that there is still a need for optimization of F-CAD for the calculation of the disintegration time in order to achieve a similar or the same performance like in the prediction of the dissolution profile of a tablet formulation. It is concluded that F-CAD software is the only software so far, which is capable of computing the disintegration time of tablets. The software has a great potential to be improved and to be not only used for the safe prediction of the dissolution profile of a tablet formulation but also for a safe prediction of the disintegration time. Thus, such a software is one of the tools for the substitution of laboratory experiments for the purpose of the design and development of new pharmaceutical solid dosage forms. The replacement of expensive laboratory experiments by in-silico experiments is an important issue to reduce development costs and to comply with the requirements of ICH Q8 exploring the design space with response surface methodology. The results of this thesis show in addition that the application of percolation theory is a must in order to detect percolation thresholds. It is important to know the response surfaces close to the percolation threshold of sensitive tablet properties such as the disintegration time to get information about the robustness of the selected formulation. In this context one has to put the question forward if the application of percolation theory should be an integral part of the guidelines of ICH Q8 exploring the formulation design space
