Browse Our Mathematics and Statistics Journals
Mathematics and statistics journals publish papers on the theory and application of mathematics, statistics, and probability. Most mathematics journals have a broad scope that encompasses most mathematical fields. These commonly include logic and foundations, algebra and number theory, analysis (including differential equations, functional analysis and operator theory), geometry, topology, combinatorics, probability and statistics, numerical analysis and computation theory, mathematical physics, etc.
When it comes to mathematics, we can classify it into pure and applied mathematics. Pure mathematics studies mathematical concepts separately from any form of mathematical application. It focuses on exploring basic ideas that make up mathematics and providing a deeper understanding of the field. It encompasses number theory, algebra, combinatorics, geometry, topology, and mathematical analysis.
On the other hand, applied mathematics encompasses the application of mathematical methods by different fields and industries. Applied mathematicians use existing theoretical knowledge and put it into practical use to solve problems in engineering, business, epidemiology, government, social sciences, and so on. Applied mathematics includes statistics, computational sciences, mathematical physics, operations research, and mathematical programming.
Statistics and probability treat the collection, organization, analysis, interpretation, and display of a large number of numerical data. For example, probability studies how often an event will happen after a certain number of repeated trials.
The mathematics and statistics journals welcome publications in the form of reviews, regular research, and short communications in all areas of pure and applied mathematics. Some articles may also publish media reviews, current trend surveys, modern theoretical techniques, and new ideas and tools in different mathematics areas.
Mathematics journals aim to encourage researchers to publish theoretical research in detail. These publications tend to become a forum for discussion of current and future field-related studies. These journals are partly open-access and only feature peer-reviewed articles.
The primary audience for these journals includes mathematicians, statisticians, graduate and undergraduate students, researchers, and other individuals interested in mathematical research.
AKJournals is proud to present its collection of six high-quality mathematics and statistics journals. Most of our journals publish papers treating both pure and applied mathematics fields: Acta Mathematica Hungarica, Mathematica Pannonica, and Periodica Mathematica Hungarica. Some journals from our collection specialize in specific areas such as scientometrics (Scientometrics), combinatorics, geometry, and topology (Studia Scientiarum Mathematicarum Hungarica), or modern and classical analysis (Analysis Mathematica).
Let k ≥ 1. A Sperner k-family is a maximum-sized subset of a finite poset that contains no chain with k + 1 elements. In 1976 Greene and Kleitman defined a lattice-ordering on the set Sk(P) of Sperner k-families of a fifinite poset P and posed the problem: “Characterize and interpret the join- and meet-irreducible elements of Sk(P),” adding, “This has apparently not been done even for the case k = 1.”
Let K = ℚ(α) be a number field generated by a complex root a of a monic irreducible polynomial ƒ (x) = x36 − m, with m ≠ ±1 a square free rational integer. In this paper, we prove that if m ≡ 2 or 3 (mod 4) and m ≠ ±1 (mod 9) then the number field K is monogenic. If m ≡ 1 (mod 4) or m ≡±1 (mod 9), then the number field K is not monogenic.
In this paper, we prove that the ∗-Ricci tensor of a real hypersurface in complex projective plane ℂP2 or complex hyperbolic plane ℂH2 is cyclic parallel if and only if the hypersurface is of type (A). We find some three-dimensional real hypersurfaces having non-vanishing and non-parallel ∗-Ricci tensors which are cyclic parallel.

Let D be a weighted oriented graph, whose underlying graph is G, and let I (D) be its edge ideal. If G has no 3-, 5-, or 7-cycles, or G is Kőnig, we characterize when I (D) is unmixed. If G has no 3- or 5-cycles, or G is Kőnig, we characterize when I (D) is Cohen–Macaulay. We prove that I (D) is unmixed if and only if I (D) is Cohen–Macaulay when G has girth greater than 7 or G is Kőnig and has no 4-cycles.
In cryptography one needs pseudorandom sequences whose short subsequences are also pseudorandom. To handle this problem, Dartyge, Gyarmati and Sárközy introduced weighted measures of pseudorandomness of binary sequences. In this paper we continue the research in this direction. We introduce weighted pseudorandom measure for multidimensional binary lattices and estimate weighted pseudorandom measure for truly random binary lattices. We also give lower bounds for weighted measures of even order and present an example by using the quadratic character of finite fields.
The symbol S(X) denotes the hyperspace of finite unions of convergent sequences in a Hausdor˛ space X. This hyper-space is endowed with the Vietoris topology. First of all, we give a characterization of convergent sequence in S(X). Then we consider some cardinal invariants on S(X), and compare the character, the pseudocharacter, the sn-character, the so-character, the network weight and cs-network weight of S(X) with the corresponding cardinal function of X. Moreover, we consider rank k-diagonal on S(X), and give a space X with a rank 2-diagonal such that S(X) does not Gδ-diagonal. Further, we study the relations of some generalized metric properties of X and its hyperspace S(X). Finally, we pose some questions about the hyperspace S(X).
Fifty years ago P. Erdős and A. Rényi published their famous paper on the new law of large numbers. In this survey, we describe numerous results and achievements which are related with this paper or motivated by it during these years.
