C1 functionA Hadamard type theorem for a C 1 -function f in a Banach space with invertible derivatives is proved: If there is some 0≤η(t)≤inf ∥x∥=t ∥f ' (x) -1 ∥ -1 which is continuous or non-increasing with infinite integral, then f is globally invertible. Moreover, ...

for some \(a,m>0\) and all \(t\ge 0\) , so the semigroup is said to be uniformly exponentially stable . a necessary condition for the uniform exponential stability of a \(c_0\) -semigroup is negativity of the spectral bound of the generator a , i.e. the condition $$\begin{...
P function g will The ? be called a g-function if g is a function from to (0; 1) and k=01 g(ix) = 1. We i will only consider those g which are continuous here. The cylinder of those points which agree with x for the rst n + 1 places (that is the set fy: yi = xi ...
a continuation of studies in [15]. In [15], we develop some explicit sufficient criteria for the existence and roughness of exponential dichotomies of linear dynamic equations on time scales. It is more interesting and more challenging to establish necessary and sufficient criteria for the ...

Figure 1 presents the theoretical relationship for selected PDFs. The exponential probabilistic density function is plotted as a point (no shape factors), the four-parameter Kappa PDF by region (two shape factors), and the rest by curves (one shape factor). The curves used to approximate the...
