摘要 本文研究一类奇异变系数拟线性抛物型不等式柯西问题中解在某个带参数的函数空间中的非线性Liouville定理。通过构造适当的试验函数来建立Universal估计值(不依赖于初始值),从而得到在适当的临界指数范围内非负非平凡整体弱解的非存在性结论。 In this paper, we investigated the nonlinear Liouville type theorems of cauchy problem fro quasi-linear parabolic inequalities with singular variable coefficients in some functional space with parameters. By constructing test function, we built universal estimate(independent of initial value), then established nonexistence result of nonnegative nontrivial global weak solution in some appropriate range of critical exponent.
