Mathematical principle is present in artwork or architectural building. It is important for middle school students to find these mathematical principles in artwork. But it is difficult to achieve original purpose of art education through student activity that only looks for mathematical principle present in artwork and architectural building. Thus, it is necessary for students to have activities to find mathematical principle in artwork for themselves through artistic experience and appreciation of artwork and to create, appreciate and express new artwork to which they apply the mathematical principle. In this article, I researched a couple of artwork or architectural buildings from this point of view in which mathematical principle is present. I also developed hypothetical teacher activities and student activities for program by providing artwork of Escher in which mathematical principle is present as an example.

In this note, we study a comparison principle for elliptic obstacle problems of p-Laplacian type with L¹-data. As a consequence, we improve some known regularity results for obstacle problems with zero Dirichlet boundary conditions.

We prove the maximum principle and the comparison principle of $p$-harmonic functions via $p$-harmonic boundary of graphs. By applying the comparison principle, we also prove the solvability of the boundary value problem of $p$-harmonic functions via $p$-harmonic boundary of graphs.

We will research the elementary formal logic and mathematical concept represented in Mojing, and focus on the ancient Chinese's mathematical principles implicit in Mojing. Moreover, the mathematical significance and values of Mojing are examined.

For convex subsets X of a topological vector space E, we show that a KKM principle implies a Fan-Browder type fixed point theorem and that this theorem implies generalized forms of the Sion minimax theorem.

We discuss the qualitative uncertainty principle for Gabor transform on certain classes of the locally compact groups, like abelian groups, ${\mathbb{R}}^n{\times}K$, K ⋉ ${\mathbb{R}}^n$ where K is compact group. We shall also prove a weaker version of qualitative uncertainty principle for Gabor transform in case of compact groups.
