Subring of constants of a ring of characteristic p>0
Let A be a local ring of characteristic p>0 which has a p-basis over a subring C, and B be the subring of constants of A for a derivation (or derivations ) of A over C. We give a sufficient condition for B to have a p-basis over C. We add some examples.

Branching rules in the ring of superclass functions of unipotent upper-triangular matrices [PDF]
It is becoming increasingly clear that the supercharacter theory of the finite group of unipotent upper-triangular matrices has a rich combinatorial structure built on set-partitions that is analogous to the partition combinatorics of the classical ...

The topological symmetric orbifold
We analyze topological orbifold conformal field theories on the symmetric product of a complex surface M. By exploiting the mathematics literature we show that a canonical quotient of the operator ring has structure constants given by Hurwitz numbers ...

Zinc oxide (ZnO) nanorods were coated on glass substrates and used as photocatalysts to evaluate the kinetic behavior of three different aromatic structures: i) single aromatic ring (phenol), ii) poly-aromatic ring (methylene blue), and iii) complex ...

We study AdS 3 × S 1 × Y supersymmetric string theory backgrounds with Neveu-Schwarz-Neveu-Schwarz flux that are dual to N $$ \mathcal{N} $$ = 2 superconformal theories on the boundary. We classify all worldsheet vertex operators that correspond to space-

This study presents a photonic bandgap formation in a non-uniform 2D photonic crystal structure with low index rods relative to the air background. In order to find an absolute photonic band gap formation, photonic lattices of two non-uniform square and ...

Constants are Definable in Rings of Analytic Functions [PDF]
The analytic functions defined in a fixed domain form a ring with pointwise addition and multiplication. We describe a way to define constants in the ring using a first-order formula which is independent of the domain.
