Rp. Agarwal et al., NONEXISTENCE OF POSITIVE SOLUTIONS FOR 2(PTH) ORDER INTEGRODIFFERENTIAL-INEQUALITIES, Applied mathematics letters, 10(6), 1997, pp. 63-69
In this paper, we shall show that under suitable conditions on f and K
, the inequalities -lambda(2p) + integral(0)(infinity) e(lambda s)K(s)
ds > 0, for all lambda > 0, (p = 0,1,2,...) imply that the integro-dif
ferential inequalities (-1)(2p+1)y((2p))(t) + integral(0)(t) f(t - s,y
(s)) ds less than or equal to 0, on [0,infinity], (p = 0,1,2,...) have
no positive solutions, respectively.
