We study representation theory of Drinfel’d twists, in terms of what we call F matrices, associated to finite dimensional irreducible modules of quantum affine algebras, and which factorize the corresponding (unitary) R-matrices. We construct explicitly such factorizing F -matrices for irreducible finite n tensor products of the fundamental evaluation representations of the quantum affine algeb...

holds, and this estimate is sharp as the family of all n2 -element subsets shows. There is a very large number of generalizations and analogues of this theorem. Here we will consider only results when the condition on F excludes certain configurations what can be expressed by inclusion, only. That is, no intersections, unions, etc. are involved. The first such generalization was obtained by Erd...

VASILEVA, S. and M. MARCHEVA, 2016. Genetic analysis of productivity components in malting barley (Hordeum vulgare, L.) hybrid progenies. Bulg. J. Agric. Sci., 22: 452–457 The investigation was conducted on the experimental fi eld of the Agricultural University of Plovdiv, during the period 2011–2014. Coeffi cients of heritability and selection, the number of genes, transgressions and heterosis...

This work presents geometrically non-linear static analysis of a cantilever beam subjected to a non-follower transversal point load at the free end of the beam. The material of the beam is assumed as isotropic and hyperelastic. In this study, finite element model of the beam is constructed by using total Lagrangian finite element model of two dimensional continua for a twelve-node quadratic ele...

The micro-scale morphology of the receding contact line dilute polyethylene oxide solution drops (c ∼ 100 ppm) after impact and inertial spreading on a fluorinated hydrophobic surface is investigated. One can observe formation transient liquid filaments dendritic structures that evolve into bead-on-a-string structure similar to well-known capillary breakup mechanism polymer solutions, which con...

The four methods of examining the relation of amount of multiple crossing over to age of mothers agree in showing that the "internode length" or average distance required for double crossing over has changed in a characteristic fashion, giving an M-shaped curve. These changes have not been independent of changes in total recombination but concomitant with them. However, the changes in recombina...
