Groups with many Subgroups which are Commensurable with some Normal Subgroup [PDF]
Advances in Group Theory and Applications, 2019 A subgroup H of a group G is called commensurable with a normal subgroup (cn) if there is N C G such that |HN/(H ∩ N)| is finite. We characterize generalized radical groups G which have one of the following finiteness conditions: (A) the minimal ...

Mathematical Modelling and Analysis, 2021 We consider the Mullins’ equation of a single surface grooving when the surface diffusion is not considered as very slow. This problem can be formed by a surface grooving of profiles in a finite space region.

Some Spectral Properties of Schrödinger Operators on Semi Axis
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023 The main aim of this work is to investigate some spectral properties of Schrödinger operators on semi axis. We first present the Schrödinger equation with a piecewise continuous potential function q so that the problem differs from the classical ...

On Classification of Semigroup N by Green’s Theorem
Journal of Mathematics, 2022 In previous papers, it has been recently defined a new class of semigroups based on both Rees matrix and completely 0-simple semigroups. For this new structure, it has been introduced with certain basic properties and finiteness conditions. The main goal

Finiteness Conditions for Light-Front Hamiltonians [PDF]
, 1997 In the context of simple models, it is shown that demanding finiteness for physical masses with respect to a longitudinal cutoff, can be used to fix the ambiguity in the renormalization of fermions masses in the Hamiltonian light-front formulation ...

Some conditions for finiteness of a ring
International Journal of Mathematics and Mathematical Sciences, 1988 Extending a result of Putcha and Yaqub, we prove that a non-nil ring must be finite if it has both ascending chain condition and descending chain condition on non-nil subrings.

Cohomological finiteness conditions for a class of metabelian groups [PDF]
, 2016 We consider a class of metabelian groups first studied by Baumslag and Stammbach and we show that these groups are consistent with the Bieri-Groves conjecture which relates cohomological finiteness conditions to the Bieri-Neumann-Strebel sigma invariant ...

Some conditions for finiteness and commutativity of rings
International Journal of Mathematics and Mathematical Sciences, 1990 We present several new sufficient conditions for a ring to be finite; we give two conditions which for periodic rings R imply that R must be either finite or commutative; and we study commutativity in rings with only finitely many non-central subrings.

Formations of Monoids, Congruences, and Formal Languages [PDF]
Scientific Annals of Computer Science, 2015 The main goal in this paper is to use a dual equivalence in automata theory started in [25] and developed in [3] to prove a general version of the Eilenberg-type theorem presented in [4].
