1 There are finitely many solutions to this problem.

2 An equilateral triangle cannot be dissected into finitely many incongruent equilateral triangles.

3 In this paper, conjugate separability problem in a finitely generated nilpotent group is researched.

4 We introduce WQF - rings, GIF - rings and SGQF - rings via the reflexiviry of finitely generated modules.

5 For most matrix of A, the linear differentiable equations with quasi - periodic finitely differentiable coefficients are reducible.

6 Generalized impedance boundary conditions are employed to simulate the effect of finitely conducting plane on the electromagnetic fields.

7 In this paper we study the linear semi-infinite programming with finitely many variables and infinitely many constraints over a compact metric space. An interior path-following approach is proposed.

8 The three - dimensional exact solution methods for dynamic problems a finitely long piezoelectric composite laminates are studied.
