On Indecomposable Vertex Algebras associated with Vertex Algebroids

Phichet Jitjankarn, Gaywalee Yamskulna

Let $A$ be a finite dimensional unital commutative associative algebra and let $B$ be a finite dimensional vertex $A$ -algebroid such that its Levi factor is isomorphic to $s l_{2}$ . U…

On Indecomposable Non-Simple $N$ -graded Vertex Algebras

Phichet Jitjankarn, Gaywalee Yamskulna

In this paper, we study an impact of Leibniz algebras on the algebraic structure of $N$ -graded vertex algebras. We provide easy ways to characterize indecomposable non-sim…

A note on Isomorphism theorems for semigroups of order-preserving transformations with restricted range

Phichet Jitjankarn, Thitarie Rungratgasame

Finding necessary and sufficient conditions for isomorphism between two semigroups of order-preserving transformations over an infinite domain with restricted range was an open pro…

A Classification of Regressive Transformation Semigroups on Chains

Patanee Udomkavanich, Phichet Jitjankarn

For each subchain $X^{'}$ of a chain $X$ , let $T_{R E} (X, X^{'})$ denote the semigroup under composition of all full regressive transformations, $α : X \to X^{'}$ satisfying $xα \leq x$ …

$C_{2}$ -cofiniteness of the vertex algebra $V_{L}^{+}$ when $L$ is a non-degenerate even lattice

Phichet Jitjankarn, Gaywalee Yamskulna

It was shown by Abe, Buhl and Dong that the vertex algebra $V_{L}^{+}$ and its irreducible weak modules satisfy the $C_{2}$ -cofiniteness condition when $L$ is a positive definite even la…
