Heterotic / Type II Triality and Instantons on K 3
A detailed understanding of instanton effects for half-BPS couplings is pursued in theories with 16 supersymmetries. In particular, we investigate the duality between heterotic string on T 4 and type IIA on K3 at the T /Z2 orbifold point, as well as their higher and lower dimensional versions. We present a remarkably clean quantitative test of the duality at the level of F 4 couplings, by compl...
متن کاملMoufang symmetry II. Moufang-Mal’tsev pairs and triality
A concept of the Moufang-Malt’tsev pair is elaborated. This concept is based on the generalized Maurer-Cartan equations of a local analytic Moufang loop. Triality can be seen as a fundamental property of such pairs. Based on triality, the Yamagutian is constructed. Properties of the Yamagutian are studied. 2000 MSC: 17D10
متن کاملInstantons beyond Topological Theory Ii
The present paper is the second part of our project in which we describe quantum field theories with instantons in a novel way by using the " infinite radius limit " (rather than the limit of free field theory) as the starting point. The theory dramatically simplifies in this limit, because the correlation functions of all, not only topological (or BPS), observables may be computed explicitly i...
متن کاملOn Correspondences of a K3 Surface with Itself. Ii
Let X be a K3 surface with a polarization H of degree H = 2rs, r, s ≥ 1, and the isotropic Mukai vector v = (r, H, s) is primitive. The moduli space of sheaves over X with the Mukai vector v = (r, H, s) is again a K3 surface, Y . We prove that Y ∼= X if the Picard lattice N(X) has an element h1 with (h1) = f(v) and minor additional congruence conditions modulo Ni(v). All these conditions are ex...
متن کاملEffects of Vitamin K3 on Cytotoxicity and DNA-binding Properties of a Palladium(II) Complex as a Potential Antitumor Agent
In many diseases such as cancer, simultaneous use of two or more pharmacologically active agents will be more effective and have fewer side effects. In this study a new palladium(II) complex with formula of [Pd(phen)(py-dtc)]NO3 (where is phen 1,10-phenanthroline and py-dtc is n-propyldithiocarbamate), was synthesized. The cytotoxic activity of this complex was tested against leukemia K562 cell...
