Extremal Steklov-Neumann Eigenvalues
Let $Ω$ be a bounded open planar domain with smooth connected boundary, $Γ$, that has been partitioned into two disjoint components, $Γ= Γ_S \sqcup Γ_N$. We consider the Steklov-Neumann eigenproblem on $Ω$, where a harmonic function is sought that satisfies the Steklov boundary condition on $Γ_S$ and the Neumann boundary condition on $Γ_N$. We pose the extremal eigenvalue problems (EEPs) of minimizing/maximizing the $k$-th non-trivial Steklov-Neumann eigenvalue among boundary partitions…

So, über die Feiertage steht mir jetzt ein gesamtes Jahr Schweizerische Eisenbahnrevue bevor.

The initial example is based of my current character and it's looking decent. I'm not happy with the skill section, but this should get the job done. Still have to figure out how I want the damage to look on weapons. I also need to get spells into the schema, but I'll leave that alone for the time being.

Direct Estimation of Eigenvalues of Large Dimensional Precision Matrix
In this paper, we consider directly estimating the eigenvalues of precision matrix, without inverting the corresponding estimator for the eigenvalues of covariance matrix. We focus on a general asymptotic regime, i.e., the large dimensional regime, where both the dimension $N$ and the sample size $K$ tend to infinity whereas their quotient $N/K$ converges to a positive constant. By utilizing tools from random matrix theory, we construct an improved estimator for eigenvalues of precision matrix.…

Eigenvalue distribution from bootstrap estimates
The bootstrap method has proven useful for a wide range of matrix models. Here, we show that the computed momenta can be used to reconstruct the underlying eigenvalue probability distribution, which in turn allows us to compute the free energy of the model, a necessary quantity for identifying the thermodynamically preferred solution. We verify the method on the well-studied quartic potential model and then apply it to a recently analysed asymmetric multi-trace model. We consider an extended cl…

CORS Simulator — A set of examples to demonstrate fundamental CORS concepts.
What’s you reaction when you see yet another CORS error in the browser? For a long time mine was to hate CORS. Then I started going DEEP on it, and discovered that much of the dynamism of modern websites wouldn’t be possible without CORS.
