Ww. Szczechla et al., ON THE PUISEUX SERIES EXPANSION OF THE LIMIT DISCOUNT EQUATION OF STOCHASTIC GAMES, SIAM journal on control and optimization, 35(3), 1997, pp. 860-875
In this paper we give a new proof of the existence of Puiseux series e
xpansion of the limit discount equation of finite state: stochastic ga
mes. Unlike the original proof, due to Bewley and Kohlberg [Math. Oper
. Res., 3 (1976), pp. 197-208], our proof is not algebraic and does no
t invoke Tarski's principle. Instead we use only the theory of functio
ns of complex variables and complex analytic varieties.
