is an irreducible (continuous) representation. We say that ρ is modular of level N , for an integer N ≥ 1, if ρ arises from cusp forms of weight 2 and trivial character on Γo(N). The term “arises from” may be interpreted in several equivalent ways. For our present purposes, it is simplest to work with maximal ideals of the Hecke algebra for weight-2 cusp forms on Γo(N). Namely, let S(N) be the ...

Let Y0(p) be the Drinfeld modular curve parameterizing Drinfeld modules of rank two over Fq[T ] of general characteristic with Hecke level p-structure, where p ⊳ Fq[T ] is a prime ideal of degree d. Let J0(p) denote the Jacobian of the unique smooth irreducible projective curve containing Y0(p). Define N(p) = q−1 q−1 , if d is odd, and define N(p) = q −1 q2−1 , otherwise. We prove that the tors...

We call a local vector lattice any vector lattice with a distinguished positive strong unit and having exactly one maximal ideal (its radical). We provide a short study of local vector lattices. In this regards, some characterizations of local vector lattices are given. For instance, we prove that a vector lattice with a distinguished strong unit is local if and only if it is clean with non no-...

‎In this paper‎, ‎we introduce the notion of the radical of a $PMV$-algebra $A$ and we charactrize radical $A$ via elements of $A$‎. ‎Also‎, ‎we introduce the notion of the radical of a $cdot$-ideal in $PMV$-algebras‎. ‎Several characterizations of this radical is given‎. ‎We define the notion of a semimaximal $cdot$-ideal in a $PMV$-algebra‎. ‎Finally we show that $A/I$ has no nilpotent elemen...

Abstract Krull’s Maximal Ideal Theorem (MIT) is one of the most prominent incarnations Axiom Choice (AC) in ring theory. For many a consequence AC, constructive counterparts are well within reach, provided attention turned to syntactical underpinning problem at hand. This viewpoints revised Hilbert Programme commutative algebra, which will here be carried out for MIT and several related classic...
