metadata.name: dc.description.abstract
metadata.value: Four models of critical behavior with quenched noise are studied by the means of renormalization
  group analysis. The models include the Kardar—Parisi—Zhang model of an interface random
  growth and its modification with an infinite number of coupling constants, the Hwa—Kardar
  model of a system in a self-organized critical state, and the model of landscape erosion with an
  infinite number of coupling constants. The quenched noise is described by the correlation function
   ff  ∝ δ(ω)/k4 (here k is a wave vector and ω is a frequency) and models variability of the studied
  profiles (e. g. growing interface, eroded landscape, etc.). For two models containing infinitely
  many coupling constants their critical exponents (that describe asymptotic — critical — behavior
  in an infrared range) satisfy a universal exact relation. For the models of the Kardar—Parisi—
  Zhang and Hwa—Kardar corresponding critical exponents are calculated to the first order of
  the expansion in the deviation from the logarithmic dimension (one-loop approximation). Refs 37.
