HYPERTRANSCENDENTAL FORMAL POWER SERIES OVER FIELDS OF POSITIVE CHARACTERISTIC
Let $K$ be a field of characteristic$p>0$, $K[[x]]$, the ring of formal power series over $ K$,$K((x))$, the quotient field of $ K[[x]]$, and $ K(x)$ the fieldof rational functions over $K$. We shall give somecharacterizations of an algebraic function $fin K((x))$ over $K$.Let $L$ be a field of characteristic zero. The power series $finL[[x]]$ is called differentially algebraic, if it satisfies...
متن کاملMatrices of positive polynomials
Associated to a squarematrix all of whose entries are real Laurent polynomials in several variables with no negative coefficients is an ordered “dimension” module introduced by Tuncel, with additional structure, which acts as an invariant for topological Markov chains, and is also an invariant for actions of tori on AF C*-algebras. In describing this invariant, we are led naturally to eventuall...

متن کاملA Property of Power Series with Positive Coefficients
The following theorem is suggested by a problem in the theory of probability .' Let pk be a sequence of non-negative numbers for which Eó pk =1, and let m = Ei kpk <_ "0. Suppose further that P(x) _ E p kx k 0 is not a power series in xl for any integer t > 1. Then 1-P(x) has no zeros in the circle I x I < 1, and the series U(x) _ u • k x k 1-P(x) 0 has the property lim u n = 1/m. n-(If m= oo, ...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
