This is a homogeneous system of linear equations, and even more, its equations are NOT independent. That is, the system has infinitely many solutions. This is because we have a family of eigenvectors (including zero vector), oreigenspace, for each eigenvalue. So, when you are asked to find...
Eigenvalues Eigenvalues are easier to explain with eigenvectors. Suppose we have a square matrixA. This matrix defines a linear transformation, that is, if we multiply any vector by A, we get the new vector that changes direction: . However, there are some vectors for which this transformation...

根据calcLimit的参数,计算会在前maxIters主要特征目标被提取后结束(这句话有点绕,应该就是提取了前int_max_iter个特征值),另一种结束的情况是:目前特征值同最大特征值的比值降至calcLimit的epsilon值之下。在这个迭代算法终止条件的约束下,于是就产生了nEigen个特征脸(object's eigen vector) 程序后两个参数,一...

(1.1) is continuous for alland is compact for all. It was pointed out to us by the referee of this paper that there may be a relation between Theorem1and the results in the recent paper [12] combined with [68] dealing the fractional Sobolev spaces defined on metric measure spaces satisf...
(1.1) where\Delta _gis the negative Laplace–Beltrami operator,\nabla _gis the gradient,\nuis the outward pointing normal vector field,Fis a force field, and\Gamma _\varepsilon \subset \partial Mis a connected piece of boundary of size\varepsilon >0. We denote the corresponding operator by...

We further suppose that the (outwards orientated) unit normal vector field nS:S⟶RN satisfies nS(X):X>0, namely the angle between the normal vector at X and the direction X itself is acute. Let α>1 and define f to be the unique α-homogeneous function on RN×n satisfying S={f=...
