The moduli space of hyper-Kähler four-fold compactifications
I discuss some aspects of the moduli space of hyper-Kähler four-fold compactifications of type II and Mtheories. The dimension of the moduli space of these theories is strictly bounded from above. As an example I study Hilb(K3) and the generalized Kummer variety K(T ). In both cases RR-flux (or G-flux in M-theory) must be turned on, and we show that they give rise to vacua with N = 2 supersymme...
متن کاملHamiltonian four fold 1:1 resonance with two rotational symmetries
This paper deals with the analysis of Hamiltonian Hopf bifurcations in 4-DOF systems defined by perturbed isotropic oscillators (1-1-1-1 resonance), in the presence of two quadratic symmetries I1 and I2. The model is a generalization of the classical models obtained from regularized Kepler systems describing the parallel Stark and Zeeman effects. After normalization the truncated normal form gi...
متن کاملStructural Bridges through Fold Space
Several protein structure classification schemes exist that partition the protein universe into structural units called folds. Yet these schemes do not discuss how these units sit relative to each other in a global structure space. In this paper we construct networks that describe such global relationships between folds in the form of structural bridges. We generate these networks using four di...
متن کاملUniversal Affine Triangle Geometry and Four - fold
We develop a generalized triangle geometry, using an arbitrary bilinear form in an affine plane over a general field. By introducing standardized coordinates we find canonical forms for some basic centers and lines. Strong concurrencies formed by quadruples of lines from the Incenter hierarchy are investigated, including joins of corresponding Incenters, Gergonne, Nagel, Spieker points, Mittenp...
متن کاملn-fold Commutative Hyper K-ideals
In this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper K-ideals. These definitions are thegeneralizations of the definitions of commutative, andimplicative hyper K-ideals, respectively, which have been definedin [12]. Then we obtain some related results. In particular wedetermine the relationships between n-fold implicative hyperK-ideal and n-fol...
