分数阶nabla差分方程振动性的充分条件（英文）

Sufficient Conditions for Oscillation of Fractional Nabla Difference Equation

建立一类非线性分数阶nabla差分方程▽(▽_α~ax(t))+f(t,x(t))= g(t)解的振动性的两个充分条件,其中,初值条件是▽_a^(-(2-α))x(a +1)=_c1 和▽▽_a^(-(2-α))x(a+1)=c_2,并给出两个例子来说明该条件是最佳的.

Two sufficient conditions for oscillation of a nonlinear fractional nabla difference equation of the form ▽（▽α~ax（t））＋f（t,x（t））= g（t）,t ∈ N（a＋1）,with initial condition▽a^（-（2-α））x（a ＋1）=c1 and▽▽a^（-（2-α））x（a＋1）=c2 are established.And two examples are presented to indicate the sharpness of our conditions.
