| Abstract: | The existence of positive entire solutions for a class of semilinear elliptic equations in Rn is discussed. By its lower and upper solutions as the main methods, the existence of the entire solutions of equations is proven under distinct conditions. The main result is that the equation has an infinite number of exponent increasing solutions and decaying solutions when its nonlinear term satisfies different conditions. |

| Keywords: | nonlinear elliptic equations positive entire solutions radial direction solutions |
