As first demonstrated by the characterization of the quantum Hall effect by the Chern number, topology provides a guiding principle to realize the robust properties of condensed-matter systems immune to the exi
Personally, I think "change of variable" is an important trick in computational math. If we can see the connection of two classes of problems using change of variables, then the algorithms designed for one class can be applied to another class. However, there are some problems. Firstly, if...

We show that this conflict can be resolved by considering an unusual function space whose definition involves the derivative ∇ ν of ν. This function space turns out to be dense subset of L 2 and the equations can be solved in the L 2-sense (as desired) by first solving an ...
{\mathcal{X}}}\)by considering the standardized real part of the inverse discrete Fourier transform. Next, we convert it to binary values (1 representing material and 0 representing void) by considering a thresholdtsampled as\(t \sim {{{\mathcal{U}}}(0,{t}_{\max })\)withtmax ...
This example shows how to derive a continuous-time nonlinear model of a quadrotor using Symbolic Math Toolbox.
The results in the following lemma either follow immediately from the definition or are easy to verify. Lemma 1.1 [2] Let A be an arbitrary matrix of size n. X and Y are two n × n positive definite matrices. Then, Without loss of generality we assume that f is multiplication ...
for some function u . clearly, u is nonnegative and quasi-concave. to show that \(u=1\) on \(\partial k\) , we take a bounded and compactly-supported function w in \({\mathcal k}_k\) . as \(0\le g^i\le g+2\) , we have $$\begin{aligned} \int _{{\mathbb r}^n\...
Abstract We prove the invariance of the Gibbs measure under the dynamics of the three-dimensional cubic wave equation, which is also known as the hyperbolicΦ34-model. This result is the hyperbolic counterpart to seminal works on the parabolicΦ34-model by Hairer (Invent. Math. 198(2):269–...
