Time-domain finite-difference (TDFD) method is the most dominant approach for seismic wavefield simulation. Due to the memory and computational cost of the computer, finite-difference (FD) simulations ...

Oscillation theory concerns the study of qualitative behaviour of solutions to differential equations, with particular focus on the presence or absence of infinitely many sign changes over unbounded ...

Hi all, this is my first post so please bear with me – any advice/support would be warmly welcomed. I have been doing some work on a simple RLC electronic circuit whose transfer function follows the ...

Mathematician Ivan Remizov from HSE University–Nizhny Novgorod and the Institute for Information Transmission Problems of the Russian Academy of Sciences has made a conceptual breakthrough in the ...

Ordinary differential equations (ODEs) are also called initial value problems because a time zero value for each first-order differential equation is needed. The following is an example of a ...

A RUDN University mathematician (Russia) and a colleague have determined the conditions for stabilization of differential inequalities that have a high order. This result will allow mathematicians to ...
