This monograph systematically reviews recent developments in population genetics. The reader can use this book either to obtain a thorough and comprehensive coverage of the present state of knowledge of the subject, and to learn new methods from it, or else to obtain an elementary introduction to the field.
Klappentext
In the theory of population genetics, fundamental results onits dynamical processes and equilibrium laws have emergedduring the last few decades. This monograph systematicallyreviews these developments, beginning from elementaryexamples and explanations.Mathematically, the main emphasis of the book is theinvestigation of iterations of a quadratic or fractionalquadratic operator in the simplex. By the use of somenon-associative algebra, many results can be obtained inexplicit form eg. the explicit description (Bernsteinproblem) of stationary quadratic operators, and the explicitsolutions of a nonlinear evolutionary equation in theabsence of selection, as well as general theorems onconvergence to equilibrium in the presence of selection.Some of the algebraic theory used is interesting for its ownsake.The reader can use this book either to obtain a thorough andcomprehensive coverage of the present state of knowledge ofthe subject, and to learn new methods from it,or else toobtain an elementary introduction to the field.
