Linear functional differential equations of mixed type are typically ill-posed, i.e., there exists, in general, no solution to a given initial condition. We prove that Fredholm properties of these ...

To define a likelihood we have to specify the form of distribution of the observations, but to define a quasi-likelihood function we need only specify a relation between the mean and variance of the ...

Consequently, the ever-widening gap between exponential progress and our linear thinking presents a significant challenge for the modern human experience.
