Trying to find a Taylor series expansion of the solutions about the point z = 0 would fail because the solutions are not analytic at z = 0 . This brings us to two important questions.
1. Can we tell if the solutions to a linear differential equation are[r]

In the textile community, it is very important to characterize cotton quality parameters since this directly affects its potential profitability. Specifically, cotton strength, length, micronaire, fineness, color, and trash amount are conventionally monitored using an Uster® High Volume In[r]

the case 3 is reduced to the case 1. We conclude that T ( D ) is equicontinuous and then is relatively compact by the Arzela–Ascoli theorem.
By applying the Schauder theorem, T has a fixed point v ∈ D (not in ∂D ) ,
that is also a solution of the problem (1.1)–(1.2) on [ − r, ∞ ) .[r]

It turns out that the general solution of any first order differential equation is a one-parameter family of functions. This is not easy to prove. However, it is easy to verify the converse. We differentiate Equation 14.1 with respect to x.

In cancer research, robustness of a complex biochemical network is one of the most relevant properties to investigate for the development of novel targeted therapies. In cancer systems biology, biological networks are typically modeled through Ordinary Differential Equation (ODE) models.

7. Conclusion
This Chapter has drawn the attention to specific features related to the safe utilization of research reactors. A summarized state-of-the-art about research reactors was presented. As it was illustrated, the rising interest in the commercial exploitation of[r]

y(t) uniquely from its n th derivative, we need n additional pieces of information (constraints) about

A solution of a differential equation is a function y(x) that, when substituted into the equation, turns it into an identity. The general solution of a differential equation is
the set of all its solutions. In some cases, the general s[r]
