Diophantine approximation exponents and continued fractions for algebraic power series

For each rational number not less than 2, we provide an explicit family of continued fractions of algebraic power series in finite characteristic (tog ether with the algebraic equations they satisfy) which has that rational nu mber as its diophantine approximation exponent. We also provide some non-qu adratic examples with bounded sequences of partial quotients. (C) 1999 Acad emic Press.
