Anomalies of non-Abelian finite groups via cobordism
We use cobordism theory to analyse anomalies of finite non-abelian symmetries in 4 spacetime dimensions. By applying the method of ‘anomaly interplay’, which uses functoriality of cobordism and naturality of the η-invariant to relate anomalies in a group

On Undecidability of Finite Subsets Theory for Torsion Abelian Groups
Let M be a commutative cancellative monoid with an element of infinite order. The binary operation can be extended to all finite subsets of M by the pointwise definition. So, we can consider the theory of finite subsets of M.

Let \(X\) be an associative ring. An \(X\)-group is a group \(G\) equipped with an action \(G\times X\to G\), \((g,x)\to g^ x\) such that \(g^ 1=g\), \((g^ x)^ y=g^{xy}\), \(g^ xg^ y=g^{x+y}\) for any \(x,y\in X\) and \(g\in G\). These groups were introduced by \textit{R. C. Lyndon} [Trans. Am. Math. Soc. 96, 518-533 (1960; Zbl 0108.02501)].

Free Boolean Topological Groups
Known and new results on free Boolean topological groups are collected. An account of the properties that these groups share with free or free Abelian topological groups and properties specific to free Boolean groups is given.

n-capability of A-groups [PDF]
Following P. Hall a soluble group whose Sylow subgroups are all abelian is called A-group. The purpose of this article is to give a new and shorter proof for a criterion on the capability of A-groups of order p2q, where p and q are distinct primes ...

Some special classes of n-abelian groups [PDF]
Let n be an integer. A group G is said to be n-abelian if the map phi_n that sends g to g^n is an endomorphism of G. Then (xy)^n=x^ny^n for all x,y in G, from which it follows [x^n,y]=[x,y]^n=[x,y^n]. It is also easy to see that a group G is n-abelian if

Many phases of generalized 3D instanton crystals
Nuclear matter at large number of colors is necessarily in a solid phase. In particular holographic nuclear matter takes the form of a crystal of instantons of the flavor group. In this article we initiate the analysis of the three-dimensional crystal

The abelianization of almost free groups [PDF]
Es wird eine Gruppe \(G\) der Mächtigkeit \(\aleph_1\) konstruiert, die nicht frei ist, aber deren abzählbare Untergruppen alle frei sind derart, dass auch die Kommutator-Faktorgruppe \(G/G'\) frei-abelsch ist. Dabei ist \(G'=[G,G]\) die Kommutator-Untergruppe von \(G\).

On Superstable Expansions of Free Abelian Groups [PDF]
We prove that $(\Z,+,0)$ has no proper superstable expansions of finite Lascar rank. Nevertheless, this structure equipped with a predicate defining powers of a given natural number is superstable of Lascar rank $ $. Additionally, our methods yield other superstable expansions such as $(\Z,+,0)$ equipped with the set of factorial elements.
