rebuilds the mountain, changes the weather, retells the jokes, remakes all the moves. — Lito …

Obtaining periodic orbits of dynamical systems is the main source of information about how
the orbits, in general, are organized. In this paper, we extend classical continuation …

Resonant solutions of the quantum Schrödinger equation occur at complex energies where
the S matrix becomes singular. Knowledge of such resonances is important in the study of …

In this contribution, we introduce numerical continuation methods and bifurcation theory,
techniques which find their roots in the study of dynamical systems, to the problem of tracing …

The ultimate goal of many a research is to develop an efficient solver for wave and scattering
problems that are described by the Helmholtz equation defined on infinite domains. With this …

In this paper, an efficient approach for continuation computation is proposed that depends
on the Levenberg Marquardt algorithm initiated with a set of random guesses. The …
