A non-reductive N = 4 superconformal algebra
A new N = 4 superconformal algebra (SCA) is presented. Its internal affine Lie algebra is based on the seven-dimensional Lie algebra su(2)⊕ g, where g should be identified with a fourdimensional non-reductive Lie algebra. Thus, it is the first known example of what we choose to call a non-reductive SCA. It contains a total of 16 generators and is obtained by a nontrivial Inönü-Wigner contractio...
متن کاملA New N = 4 Superconformal Algebra
It is shown that the previously known N = 3 and N = 4 superconformal algebras can be contracted consistently by singular scaling of some of the generators. For the later case, by a contraction which depends on the central term, we obtain a new N = 4 superconformal algebra which contains an SU(2)×U(1) Kac-Moody subalgebra and has nonzero central extension.
متن کاملBRST operator for the large N=4 superconformal algebra.
We review the detailed structure of the large N = 4 superconformal algebra, and construct its BRST operator which constitutes the main object for analyzing N = 4 strings. We then derive the general condition for the nilpotency of the BRST operator and show that there exists a line of critical N = 4 string theories. e-mail address: [email protected] e-mail address: [email protected], ohta@...
متن کاملCentral Extensions of the Heisenberg Algebra
Abstract. We study the non-trivial central extensions CEHeis of the Heisenberg algebra Heis recently constructed in [1]. We prove that a real form of CEHeis is one the fifteen classified real four–dimensional solvable Lie algebras. We also show that CEHeis can be realized (i) as a sub–Lie–algebra of the Schroedinger algebra and (ii) in terms of two independent copies of the canonical commutatio...
متن کاملSuperconformal transformations of the N = 4 supersymmetric
The N = 4 supersymmetric Yang-Mills theory (SSYM) has many interesting properties, one of them being its finiteness to all orders in perturbation (Mandelstam 1983; Howe et a11983; Brink et al 1983; Salam et a11983). One of the ways to prove finiteness (Sohnius and West 1981), relies on the fact that the N = 4 superconformal (SC) algebra does not involve the chiral-R charge. In this paper we obt...
