Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Abstract: Automatically solving math word problems is a critical task in the field of natural language processing. Recent models have reached their performance bottleneck and require more high-quality ...

Abstract: Time-dependent Lyapunov matrix equation (TDLME) plays a central role in the control of linear and nonlinear systems. Existing models, including the classical zeroing neural dynamics (ZNDs) ...

The internet is torn over an elementary-level math equation which left many scratching their heads. The viral math problem has X users stumped - but the answer comes from lessons learned in fifth or ...

We show how to prescribe the initial data of a characteristic problem satisfying the constraints, the smallness, the regularity and the asymptotic decay suitable to prove a global existence result. In ...

We study the Neumann problem for complex special Lagrangian equations with critical phase. A priori derivative estimates up to order two are established. And we obtain the existence and uniqueness ...

Nissan will reportedly reduce the production output of the new Leaf electric crossover in Japan. The cause for the production cut is caused by lower than expected output at Nissan’s battery supplier.
