Yang–Baxter operators and scattering amplitudes in N=4 super-Yang–Mills theory
Abstract Yangian symmetry of amplitudes in N = 4 super-Yang–Mills theory is formulated in terms of eigenvalue relations for monodromy matrix operators. The Quantum Inverse Scattering Method providesExpand

Cercosporella and Ramularia
Cercosporella and Ramularia (hyphomycetous anamorphs with relationship to Mycosphaerellaceae, Ascomycota) are difficult to distinguish based on light microscopic characteristics of conidiophores andExpand

Phylogenetic relationships and new records of Asterinaceae (Dothideomycetes) from Panama
Asterinaceae are small obligately biotrophic pathogens growing superficially on living leaves of higher plants in tropical and subtropical regions worldwide. The species-rich but rarely studiedExpand

Generalized Lipatov-Altarelli-Parisi equations and jet calculus rules
Abstract Within the leading logarithmic approximation of QCD using a method by Lipatov we derive generalized Lipatov-Altarelli-Parisi equations for the m -parton distributions from which the jetExpand

Cuniculitrema polymorpha (Tremellales, gen. nov. and sp. nov.), a heterobasidiomycete vectored by bark beetles, which is the teleomorph of Sterigmatosporidium polymorphuma
In a study of the mycobiota associated with bark beetles, a dimorphic fungus producing longitudinally septate basidia of the Tremella-type and yeast cells budding off from stalks, was collected.Expand

Two cheirosporous hyphomycetes reassessed based on morphological and molecular examination
Based on own collections, two species of cheirosporous hyphomycetes (anamorphic Pleosporales) have been reexamined by morphology and molecular analysis. Cheiromyces inflatus is a new record forExpand

Two new species of Pyxidiophora associated with bark beetles in Europe
Two new species of Pyxidiophora (Ascomycota, Laboulbeniomycetes, Pyxidiophorales) associated with bark beetles (Coleoptera, Scolytidae) colonising the sapwood and secondary phloem of conifers (LarixExpand

Baxter operators with deformed symmetry
Abstract Baxter operators are constructed for quantum spin chains with deformed sl 2 symmetry. The parallel treatment of Yang–Baxter operators for the cases of undeformed, trigonometrically andExpand

Baxter operators for arbitrary spin
We construct Baxter operators for the homogeneous closed XXX spin chain with the quantum space carrying infinite or finite dimensional sl2 representations. All algebraic relations of Baxter operatorsExpand
