On the uniqueness of zero solution of Hammerstein type

integral inclusions

Consider problem on the existence of solution of the following inclusion

Let multimap satisfies the following conditions (see [1]):

for every the multifunction has a measurable selection;

the multimap is under semicontinuous for a.e. ;

denotes the collection of all linear operators in and let be an operator satisfying the following properties:

such that for all and a.e. ;

for every multifunction is measurable, ;

, multifunction is continuous by uniformly relatively to , т.е. , such that , from follow ,

for all .

Theorem 1. let kernel satisfies the conditions and multimap satisfies the conditions . Assume that:

there exits a function such that

, for all and a.e. ;

, where - constant from condition .

Then the integral inclusion (1) has only zero solution.

Let multimap is almost lower semicontinuous (see [1]).

Theorem 2. let kernel satisfies the conditions , and multimap is almost lower semicontinuous. Assume that, there exit a number and a function such that

,

for all and a.e. ;

.

Then the integral inclusion (1) has only zero solution.

Theorem 3. let kernel satisfies the conditions , multimap is almost lower semicontinuous and satisfies the conditions and . Then the integral inclusion (1) has only zero solution.
