We propose an abstraction scheme for soft constraint problems and we study its main properties. Processing the abstracted version of a soft constraint problem can help us in many ways: for example, to find good approximations of the optimal solutions, or also to provide us with information that can make the subsequent search for the best solution easier. The results of this paper show that the proposed scheme is promising; thus they can b..
Semisimple flat F-manifolds in higher genus
No full textIn this paper, we generalize the Givental theory for Frobenius manifolds and
cohomological field theories to flat F-manifolds and F-cohomological field
theories. In particular, we define a notion of Givental cone for flat
F-manifolds, and we provide a generalization of the Givental group as a matrix
loop group acting on them. We show that this action is transitive on semisimple
flat F-manifolds. We then extend this action to F-cohomological field theories
in all genera. We show that, given a semisimple flat F-manifold and a Givental
group element connecting it to the constant flat F-manifold at its origin, one
can construct a family of F-CohFTs in all genera, parameterized by a vector in
the associative algebra at the origin, whose genus part is the given flat
F-manifold. If the flat F-manifold is homogeneous, then the associated family
of F-CohFTs contains a subfamily of homogeneous F-CohFTs. However, unlike in
the case of Frobenius manifolds and CohFTs, these homogeneous F-CohFTs can have
different conformal dimensions, which are determined by the properties of a
certain metric associated to the flat F-manifold.Comment: v2: minor corrections, accepted for publication version, 49 page
Flat F-Manifolds, F-CohFTs, and Integrable Hierarchies
No full textWe define the double ramification hierarchy associated to an F-cohomological field theory and use this construction to prove that the principal hierarchy of any semisimple (homogeneous) flat F-manifold possesses a (homogeneous) integrable dispersive deformation at all orders in the dispersion parameter. The proof is based on the reconstruction of an F-CohFT starting from a semisimple flat F-manifold and additional data in genus 1, obtained in our previous work. Our construction of these dispersive deformations is quite explicit and we compute several examples. In particular, we provide a complete classification of rank 1 hierarchies of DR type at the order 9 approximation in the dispersion parameter and of homogeneous DR hierarchies associated with all 2-dimensional homogeneous flat F-manifolds at genus 1 approximation
Leptonic decay constants f(K), f(D), and f(Ds) with N-f=2+1+1 twisted-mass lattice QCD
No full textWe present a lattice QCD calculation of the pseudoscalar decay constants f(K), f(D) and f(Ds) performed using the gauge configurations produced by the European Twisted Mass Collaboration with N-f = 2 + 1 + 1 dynamical quarks, which include in the sea, besides two light mass degenerate quarks, also the strange and charm quarks with masses close to their values in the real world. The simulations are based on a unitary setup for the two light mass-degenerate quarks and on a mixed action approach for the strange and charm quarks. We use data simulated at three different values of the lattice spacing in the range 0.06-0.09 fm and at pion masses in the range 210-450 MeV. Our main results are f(K+)/f(pi+) = 1.184(16), f(K+) = 154.4(2.0) MeV, which incorporate the leading strong isospin breaking correction due to the up and down quark mass difference, and f(K) = 155.0(1.9) MeV, f(D) = 207.4(3.8) MeV, f(Ds) = 247.2(4.1) MeV, f(Ds)/f(D) = 1.192(22) and (f(Ds)/f(D))/(f(K)/f(pi)) = 1.003(14) obtained in the isospin symmetric limit of QCD. Combined with the experimental measurements of the leptonic decay rates of kaon, pion, D and D-s mesons our results lead to the following determination of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements: vertical bar V-us vertical bar = 0.2269(29), vertical bar V-cd vertical bar = 0.2221(67) and vertical bar V-cs vertical bar = 1.014(24). Using the latest value of vertical bar V-ud vertical bar from superallowed nuclear beta decays the unitarity of the first row of the CKM matrix is fulfilled at the per mill level
