Correct classification remains a challenge for researchers and practitioners developing algorithms. Even a minor enhancement in classification quality, for instance, can significantly boost the effectiveness of detecting conditions or anomalies in sa

The classical n-body problem in physics addresses the prediction of individual motions of a group of celestial bodies under gravitational forces and has been studied since Isaac Newton formulated his laws. Nowadays the n-body problem has been recogni

In biomedical papers resulting from the cooperation of a biomedical team and a statistical team, the leader of the statistical team is traditionally placed second-to-last in the authors’ list. In many papers, the leader of the statistical team desi

We study a mathematical model of cell populations dynamics proposed by J. Lebowitz and S. Rubinow, and analysed by M. Rotenberg. Here, a cell is characterized by her maturity and speed of maturation. The growth of cell populations is described by a p

We discuss the uniform exponential stability of strongly continuous semigroups generated by operators of the form $$ A+B $$ A + B , where B is a bounded perturbation of a generator A. We compare two approaches to the problem: via the Dyson–Phillips

It is shown that if two cosine families with values in a normed algebra with unity, both indexed by t running over all real numbers, of which one consists of the multiples of the unity of the algebra by numbers of the form cos a t for some real a

Let \( C[0,1] \) be the space of continuous functions on the unit interval \( [0,1] \). A cosine family $\{C(t), t \in \mathbb{R}\}$ in $C[0,1]$ is said to be Laplace-operator generated, if its generator is a restriction of the Laplace operator $L\co

We use Kelvin’s method of images (Bobrowski in J. Evol. Equ. 10(3):663–675, 2010; Semigroup Forum 81(3):435–445, 2010) to show that given two non-negative integers $i\not= j$ there exists a unique cosine family generated by a restriction of the
