This article surveys the recent developments in computational methods for second order fully nonlinear partial differential equations (PDEs), a relatively new subarea within numerical PDEs. Due to ...

In 1956, the American geologist M. King Hubbert made a startling prediction: In a matter of decades, the supply of fuel on which so much of modern society depended would dwindle. Dubbed the “peak oil” ...

A back-to-basics brain teaser is dividing the internet. BholanathDutta shared the sum 100 + 100 × 4 = ? on X, formerly Twitter, sparking debate among users. At first glance, many people speed to the ...

Abstract: This paper focuses on distributed fixed-time tracking consensus and containment control problems of second-order multi-agent systems (MASs) with directed topology. To make the offline design ...

This article addresses an adaptive backstepping finite-time optimal formation control problem for second-order multiagent systems (MASs) with unknown nonlinear dynamics. Neural networks (NNs) are used ...

SC’s stray dog order fails Delhi. Courtroom absolutes don’t solve bad policy What’s needed now is a policy-based solution. The situation cannot remain suspended between denial and inaction—it has ...

The subject of Prof. Titchmarsh's book is the expansion of an arbitrary function in terms of the eigenfunctions of linear differential equations; to be precise, in terms of functions which satisfy an ...
