چکیده
Proper symmetries act on fields while pseudo-symmetries act on both fields and coupling constants. We identify the pseudo-duality groups that act as symmetries of the equations of motion of general systems of scalar and vector fields and apply our results to N = 2, 4 and 8 supergravity theories. We present evidence that the pseudo-duality group for both the heterotic and type II strings toroidally compactified to four dimensions is Sp(56; Z Z) × D, where D is a certain subgroup of the diffeomorphism group of the scalar field target space. This contains the conjectured heterotic S × T or type II U proper duality group as a subgroup.

Electric/magnetic Duality and Its Stringy Origins
We review electric/magnetic duality in N = 4 (and certain N = 2) globally supersymmetric gauge theories and show how this duality, which relates strong to weak coupling, follows as a consequence of a string/string duality. Black holes, eleven dimensions and supermembranes also have a part to play in the big picture. Based on review talks delivered at the PASCOS 95 conference, Johns Hopkins Univ...
متن کاملOn the duality of quadratic minimization problems using pseudo inverses
In this paper we consider the minimization of a positive semidefinite quadratic form, having a singular corresponding matrix $H$. We state the dual formulation of the original problem and treat both problems only using the vectors $x in mathcal{N}(H)^perp$ instead of the classical approach of convex optimization techniques such as the null space method. Given this approach and based on t...
متن کاملDuality of $g$-Bessel sequences and some results about RIP $g$-frames
In this paper, first we develop the duality concept for $g$-Bessel sequences and Bessel fusion sequences in Hilbert spaces. We obtain some results about dual, pseudo-dual and approximate dual of frames and fusion frames. We also expand every $g$-Bessel sequence to a frame by summing some elements. We define the restricted isometry property for $g$-frames and generalize some resu...

Target space duality symmetries, which acts on Kähler and continuous Wilson line moduli, of a Z N (N = 2) 2-dimensional subspace of the moduli space of orbifold compactification are modified to include twisted moduli. These spaces described by the cosets SU (n,1) SU (n)×U (1) are special Kähler, a fact which is exploited in deriving the extension of tree level duality transformation to include ...
