On the Lq-reflector problem in ℝn with non-Euclidean norm
In this article, we introduce a class of geometric optics measure-the LqΣ{L}_{q}\hspace{0.33em}\Sigma -reflector measure which arises from an Lq{L}_{q} extension of the Σ\Sigma -reflector measure.

An overdetermined problem for the anisotropic capacity [PDF]
We consider an overdetermined problem for the Finsler Laplacian in the exterior of a convex domain in $\mathbb{R}^N$, establishing a symmetry result for the anisotropic capacitary potential. Our result extends the one of W. Reichel [Arch.

A short proof of the infinitesimal Hilbertianity of the weighted Euclidean space
We provide a quick proof of the following known result: the Sobolev space associated with the Euclidean space, endowed with the Euclidean distance and an arbitrary Radon measure, is Hilbert.

On the norms and Hadamard product of Toeplitz matrices involving Leonardo numbers [PDF]
In this study, we consider the Toeplitz matrices with entries being Leonardo numbers. We have found upper and lower bounds for the spectral norms of these matrices, considering also the Hadamard product of this type of matrix.

Some generalized Euclidean and 2-stage Euclidean number fields that are not norm-Euclidean [PDF]
We give examples of Generalized Euclidean but not norm-Euclidean number fields of degree greater than 2. In the same way we give examples of 2-stage Euclidean but not norm-Euclidean number fields of degree greater than 2. In both cases, no such examples were known.

The Pólya-Szegö Principle and the Anisotropic Convex Lorentz-Sobolev Inequality
An anisotropic convex Lorentz-Sobolev inequality is established, which extends Ludwig, Xiao, and Zhang’s result to any norm from Euclidean norm, and the geometric analogue of this inequality is given.

We present a new proof of the Pythagorean theorem which suggests a particular decomposition of the elements of a topological algebra in terms of an “inverse norm” (addressing unital algebraic structure rather than simply vector space structure).

A Wave-function for Stringy Universes [PDF]
We define a wave-function for string theory cosmological backgrounds. We give a prescription for computing its norm following an earlier analysis within general relativity.

On Skew Circulant Type Matrices Involving Any Continuous Fibonacci Numbers
Circulant and skew circulant matrices have become an important tool in networks engineering. In this paper, we consider skew circulant type matrices with any continuous Fibonacci numbers.

Eigenvalue bounds for non-self-adjoint Schr\"odinger operators with non-trapping metrics [PDF]
We study eigenvalues of non-self-adjoint Schr\"odinger operators on non-trapping asymptotically conic manifolds of dimension $n\ge 3$. Specifically, we are concerned with the following two types of estimates.
