where the weight function a\in C[0,1] has indefinite sign. Recently, Wang and An [66] dealt with the existence and multiplicity of positive solutions for the second-order differential system \textstyle\begin{cases} -u''= a(t)\varphi u+h(t)f(u), \quad 0< t< 1, \\ -\varphi...

The class of the holonomic functions is closed under the operations of sum, product, indefinite integration, differentiation, right composition with algebraic functions. Furthermore, given two differential equations (of order d1 and d2, respectively) satisfied by two holonomic functions f1(x) and f2...
It would be risky for controlling shareholders to use debt to scale their vision without giving up control: because of fundamental uncertainty, the near-term returns on the vision are unpredictable.156 The advantage of equity is the indefinite time horizon to repay financiers. Dual-class shares ...
the ‘crisis of democracy’ – comes “from the internal dynamics of democracy itself in a highly educated, mobilized, and participant society,” and that what is needed is “a more balanced existence” in which there are “desirable limits to the indefinite extension of political...

In [12]. with the development of a dynamic level control method using Gaussian networks, a controller for non-linear toxins in the form of strict feedback with desired indeterminacy is presented. In [13], the problem of adaptive tracking control for a class of indeterminate strict single ...
