Mathematical models of real-world phenomena are often nonlinear and too complicated to be solved exactly. Thus, new mathematical methods are required to analyse these models and determine what their ...

A research team has discovered a surprising phenomenon that could revolutionize how we think about signal amplification. Just two tiny vibrating units can, when connected with a delay, amplify their ...

Under investigation in this paper is a (2+1)-dimensional nonlinear Schrödinger equation (NLS), which is a generalisation of the NLS equation. By virtue of Wronskian determinants, an effective method ...

Science Progress (1933-), Vol. 104, No. 4 (2021), pp. 1-26 (26 pages) Singularity is one of the important features in invariant structures in several physical phenomena reflected often in the ...
