We consider the Cauchy problem for an ordinary fractional differential inequality with a polynomial nonlinearity with variable coefficient. A nonexistence result is proved and the critical exponent separating existence from nonexistence is found. This is proved in the absence of any regularity assum
Techniques for finding bounds on the lowest eigenvalue, 2~, of the problem Au + 2u = 0 in D, Ol . \_2t = On zuon OD(z> 0), are discussed, and some properties of 2t and ui are derived. The problem arises in acoustic propagation in elastic tubes. The lowest eigenvalue is negative, and corresponds to a
