On simpleness of semirings and complete semirings [PDF]
In this paper, we investigate various classes of semirings and complete semirings regarding the property of being ideal-simple, congruence-simple, or both. Among other results, we describe (complete) simple, i.e. simultaneously ideal- and congruence-simple, endomorphism semirings of (complete) idempotent commutative monoids; we show that the concepts ...

AbstractWe prove that each element of a complete atomic $ l $-semiring has a canonical decomposition. We also find some sufficient conditions for the decomposition to be unique that are expressed by first-order sentences. As a corollary, we obtain a theorem of Avgustinovich–Frid which claims that each factorial language has the unique canonical ...

*-μ-semirings and *-λ-semirings
AbstractWe introduce and study *-μ-semirings and *-λ-semirings which generalize inductive *-semirings and weak inductive *-semirings, respectively. Also, we discuss the semiring of formal power series with coefficients in such a semiring and prove that the semiring of formal power series with coefficients in a weak inductive *-semiring [μ-semiring, λ ...

Translations in semirings and semiring of translations
In this paper we describe the inner left [right] translations and bitranslations on a semiring \(s\) and it is shown that these translations in semirings provides representations of the semiring. In particular, here it is shown that the translations on a \(\Gamma\)-semiring is again a \(\Gamma\)-semiring.

Invertible Ideals and Gaussian Semirings [PDF]
In the first section of this paper, we introduce the notions of fractional and invertible ideals of semirings and characterize invertible ideals of a semidomain.

On the Content of Polynomials Over Semirings and Its Applications [PDF]
In this paper, we prove that Dedekind-Mertens lemma holds only for those semimodules whose subsemimodules are subtractive. We introduce Gaussian semirings and prove that bounded distributive lattices are Gaussian semirings.

One of the most well-known induction principles in computer science<br />is the fixed point induction rule, or least pre-fixed point rule. Inductive <br />*-semirings are partially ordered semirings equipped with a star operation<br />satisfying the fixed point equation and the fixed point induction rule for<br />linear terms ...

Let \((S,+)\) be a semigroup and \(p>0\) an integer. If for any \(x\in S\) there exists some \(y\in S\) such that \(x+py+x=y\) and \(py+x+py=x\) then \((S,+)\) is called a \(p\)-semigroup. Near at hand examples are idempotent semigroups and groups which satisfy \(x+x=0\) for all \(x\in S\). A semiring \((S,+,\cdot)\) is called a \(p\)-semiring if \((S,+

Positivstellensätze for semirings
AbstractIn this paper we develop a number of results and notions concerning Positivstellensätze for semirings (preprimes) of commutative unital real algebras. First we reduce the Archimedean Positivstellensatz for semirings to the corresponding result for quadratic modules.
