Lines on Fano hypersurfaces
… that the Hilbert scheme of lines on any smooth Fano hypersurface of degree d =/< 6 in ... has the expected dimension 2n - d - 3, if k is an algebraically closed field of characteristic zero.

Globale Deformation spezieller Fano 3-Mannigfaltigkeiten
Die Dissertation "Globale Deformation spezieller Fano 3-Mannigfaltigkeiten" beschäftigt sich mit der globalen Deformation von Fano Mannigfaltigkeiten mit Dimension 3 und Picardzahl 1. Genauer gesagt wird die Frage untersucht, ob die Tatsache, dass für eine glatte Familie kompakter komplexer …

K-stability of Log Fano Cone Singularities
In this thesis, we define the 𝛿-invariant for log Fano cone singularities, and show that the necessary and sufficient condition for K-semistability is 𝛿 ≥ 1. This generalizes the result of C. Li and K. Fujita. We also prove that on any log Fano cone singularity of dimension 𝑛 whose 𝛿-invariant is …

Time-Dependent Solution of the Generalized Fano Model
… blížící se konstantnímu chová podle predikce Fanova modelu a diskrétní stav se exponenciálně rozpadá do kontinua. Pro výrazně nekonstantní coupling systém osciluje mezi počátečním diksrétním stavem a kontinuem. Práce předkládá numericky spočtený časový vývoj pro různé formy couplingu, stručnou …

Subradiant, superradiant and Fano resonances in dimer and ring/disk nanocavities
… parent plasmons. We observe the appearance of Fano resonances in the optical response of plasmonic nanocavities due to the coherent coupling between their superradiant and subradiant plasmon modes due to structural symmetry breaking. Both subradiant modes and Fano resonances exhibit substantial …

From fano to nano: mechanisms and applications of surface enhanced raman spectroscopy
… asymmetric peak shapes can result, known as Fano resonances. This may be useful in SERS: more energy confined to the region near the nanostructures and proximal analyte molecules, provides a larger SERS enhancement. In the literature, there appears to be an evasion of an experimental SERS …

Plasmonic Nanostructures: Optical Nanocircuits, Tunable Charge Transfer Plasmons, and Properties of Fano Resonant Nanoclusters
… New interesting properties emerge, such as the Fano resonance, when clusters of nanoparticles are brought into close proximities. The reduced light scattering within the Fano resonance corresponds to the intense local fields around and within the clusters, a promising feature for the development …

Complements on Log Canonical Fano Varieties and Index Conjecture of Log Calabi-Yau Varieties
… the theory of complements to log canonical Fano varieties and relate theory of complements to the index conjecture of log Calabi-Yau varieties. We mainly work over an algebraically closed field of characteristic zero, more specifically over C. We will first introduce some basic background …

On the Quantum Cohomology of Fano Toric Manifolds and the Intersection Cohomology of Singular Symplectic Quotients
The second result computes the intersection cohomology of the singular symplectic reduced spaces. Let M be a closed symplectic manifold with a Hamiltonian S1-action defined on it and mu is the moment map. If 0 is a singular value of mu, the reduced space mu-1(0)/S1 is, in general, no longer an …

Plasmon hybridization in real metals
… that the extinction spectrum exhibited a narrow Fano resonance. Using the plasmon hybridization approach and group theory we showed that this Fano resonance is caused by the interference of two bonding dipolar subradiant and superradiant plasmon modes of E1u symmetry. We investigate the effect of …

Maximum-Sized Matroids with no Minors Isomorphic to U2,5, F7, F7¯, OR P7
… which do not contain the 5-point line U2,5 , the Fano plane F7 , the non-Fano plane F7- , or the matroid P7 , as minors. Let h(n) be the maximum number of points in a rank-n matroid in M. We show that h(2)=4, h(3)=7, and h(n)=n(n+1)/2 for n>3, and we also find all the maximum-sized matroids for …

The topology of terminal quartic 3-folds
… More generally, let Y be a terminal Gorenstein Fano 3-fold with Picard rank 1. Denote by s(Y )=h_4 (Y )-h^2 (Y ) = h_4 (Y )-1 the defect of Y. A variety is Q-factorial when every Weil divisor is Q-Cartier. The defect of Y is non-zero precisely when the Fano 3-fold Y is not Q-factorial. Very …

Variability of Neural Responses in the Lateral Prefrontal Cortex

Dynamic alpha-invariants of del Pezzo surfaces with boundary
… plays an important role in the geometry of Fano varieties. Tian showed that Fano manifolds with big alpha-invariant can be equipped with a Kahler-Einstein metric. In recent years Donaldson drafted a programme to determine when a smooth Fano variety X admits a Kahler-Einstein metric. It was …

Periodic subwavelength photonic structures

Log geometry and extremal contractions
