 note = {The existence of positive solutions to the system of ordinary differential
equations related to the Belousov-Zhabotinsky reaction is
established. The key idea is to use a new successive approximation
of solutions, ensuring its positivity. To obtain the positivity and
invariant region for numerical solutions, the system is discretized as
difference equations of explicit form, employing operator splitting
methods with linear stability conditions. Algorithm to solve the
alternate solution is given.},
