The nonexistence of a profile in this example is due to the presence of a limit cycle in the vector field associated with the viscous profile entropy criterion.
At last, in "Two illustrating examples" section, we give some examples for the existence and nonexistence of the optimal feedback control operator.
"This hearing was just one more example of the nonexistence of the rule of law in Ukraine," she said.
Next, we give a negative example to show the nonexistence of the desired optimal feedback operator.
For example, the existence or nonexistence of immortal beings is outside the realm of humanism, which concerns itself with mortal human only.
At first, we provide a topological principle to design a discontinuous surface to get rid of the nonexistence of continuous stabilizing feedback, with a pair of illustrative examples of single-generator case.
In Section 4, we investigate the nonexistence of positive solutions of (S - BC); and in S - BCn 5, some exandles are ginen to Section our results.
Some papers considered the existence, multiplicity, and nonexistence of positive solutions for fourth-order impulsive differential equations with one-dimensional m-Laplacian; for example, see [13 17].
For example, in [9, 10], Bǎleanu et al. investigated the existence and nonexistence of the solutions for initial value problem of the following linear sequential fractional differential equation: bigl(D_{0}^{alpha}ybigr)'+a(x y=0, quad x>0.
The above examples illustrate that suitably chosen impulses may control the forcing term in order to get existence or nonexistence of periodic solutions.
