A quasisymmetric mapping is a homeomorphism of the circle with the property that it does not distort cross ratios too badly. By a theorem of Beurling and Ahlfors such maps are precisely the boundary values of quasiconformal homeomorphisms of the disk. A group [italic]G of quasis…
"This monograph studies a series of mathematical models of the evolution of a population under mutation and selection. Its starting point is the quasispecies equation, a general non-linear equation which describes the mutation-selection equilibrium in Manfred Eigen's famous quas…
