If every centralizer-closed set is the set of all solutions of a system of equations over a finite algebra, then we say that the algebra has Property (SDC). Our main result is the description of finite lattices and semilattices with Property (SDC): we prove that a finite lattice has ...
Villegas theorem says that, in a finite group, the number of solutions to a system of coefficient-free equations is divisible by the order of the group if the rank of the matrix composed of the exponent sums of the j-th unknown in the i-th equation is less than the number of unknown...

An example of an equation with no solution is x = x + 5. An example of a system of equations with no solution is: x + 3y = 5 2x + 6y = 7. What is a system of equations that has no solution? A system of equations that has no solution is a set of functions for which ...

A New Method for Global Solution of Systems of Non-Linear Equations In this paper the problem of finding the set of all real solutions to a system of n non-linear equations contained in a given n-dimensional box (the global solution problem) is considered. A new method for solving the gl...
