For a radical monomial ideal I in a normal semigroup ring k[Q], there is a unique minimal irreducible resolution 0 → k[Q]/I → W 0 → W 1 → · · · by modules W i of the form ⊕ j k[Fij ], where the Fij are (not necessarily distinct) faces of Q. That is, W i is a direct sum of quotients of k[Q] by prime ideals. This paper characterizes Cohen–Macaulay quotients k[Q]/I as those whose minimal irreducib...
Let F be the finite field of q elements and let P(n, q) be the projective space of dimension n−1 over F. We construct a family H k,i of combinatorial homology modules associated to P(n, q) over a coefficient field F field of characteristic p0 > 0 co-prime to q. As FGL(n, q) -representations the modules are obtained from the permutation action of GL(n, q) on the subspaces of F. We prove a branch...
The weight and the depth of ζ(k1, . . . , km) are k1 + · · ·+ km and m, respectively. Recently, MZVs have been studied extensively in number theory [Go, Z], knot theory [LM], mirror symmetry [H3] and perturbative quantum field theory [Kr]. Many relations of MZVs, for example Hoffman’s relation [H1], the duality formula [Z], the sum formula [Gr], Le-Murakami’s relation [LM] and the cyclic sum fo...
We present experimental results of the first high-precision test of quark-hadron duality in the spin-structure function g_{1} of the neutron and 3He using a polarized 3He target in the four-momentum-transfer-squared range from 0.7 to 4.0 (GeV/c);{2}. Global duality is observed for the spin-structure function g_{1} down to at least Q;{2}=1.8 (GeV/c);{2} in both targets. We have also formed the p...
We use S-duality and planarity to propose an argument for the non-renormalization of the dispersion relation of giant magnon solutions in type IIB string theory on Ad S5 × S5. We compute the spectrum of giant magnons for (p, q)-strings from field theory at strong coupling by using the central charge properties of electrically and magnetically charged supersymmetric states in the Coulomb branch ...
We explore the physics of the parton-hadron duality in the nucleon structure functions appearing in lepton-nucleon scattering. We stress that the duality allows one to extract the higher-twist matrix elements from data in the resonance region, and learn about the properties of resonances if these matrix elements are known. As an example, we construct the moments of F2(x,Q 2) for the low and med...
We propose a manifestly U–duality invariant modular form for the D4R4 interaction in type IIB string theory compactified on T 2. It receives perturbative contributions upto two loops, and non–perturbative contributions from D–instantons and (p, q) string instantons wrapping T 2. We provide evidence for this modular form by showing that the coefficients at tree level and at one loop precisely ma...
I propose that self–duality in quantum phase–space provides the criteria for the selection of the quantum gravity vacuum. The evidence for this assertion arises from two independent considerations. The first is the phenomenological success of the free fermionic heterotic–string models, which are constructed in the vicinity of the self–dual point under T–duality. The relation between the free fe...
