Solutions to the Problem of K-SAT / K-COL Phase Transition Location
  As general theories, currently there are concentration inequalities (of random walk) only for the cases of independence and martingale differences. In this paper, the concentration inequalities are extended to more general situations. In terms of the theory presented in the paper, the condition of independence is $\frac { \partial y } {\partial t}=$ constant and martingale difference's is $\frac { \partial y } {\partial t} = 0 $. This paper relaxes these conditions to $\frac { \partial^2 y } {\partial u_i \partial t} \le L$; i.e. $\frac { \partial y } {\partial t}$ can vary. Further, the concentration inequalities are extended to branching random walk, the applications of which solve some long standing open problems, including the well known problems of K-SAT and K-COL phase transition locations, among others.
