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).
Infinite matroids have been defined by Reinhard Diestel and coauthors in such a way that this class is (together with the finite matroids) closed under dualization and taking minors. On the other hand, Andreas Dress introduced a theory of matroids with coefficients in a fuzzy ring which is – from a combinatorial point of view – less general, because within this theory every circuit has a finite intersection with every cocircuit. Within the present paper, we extend the theory of matroids with coefficients to more general classes of matroids, if the underlying fuzzy ring has certain properties to be specified.
In many clique search algorithms well coloring of the nodes is employed to find an upper bound of the clique number of the given graph. In an earlier work a non-traditional edge coloring scheme was proposed to get upper bounds that are typically better than the one provided by the well coloring of the nodes. In this paper we will show that the same scheme for well coloring of the edges can be used to find lower bounds for the clique number of the given graph. In order to assess the performance of the procedure we carried out numerical experiments.
This paper solves an enumerative problem which arises naturally in the context of Pascal’s hexagram. We prove that a general Desargues configuration in the plane is associated to six conical sextuples via the theorems of Pascal and Kirkman. Moreover, the Galois group associated to this problem is isomorphic to the symmetric group on six letters.

The purpose of this paper is to study the principal fibre bundle (P, M, G, πp ) with Lie group G, where M admits Lorentzian almost paracontact structure (Ø, ξp, ηp, g) satisfying certain condtions on (1, 1) tensor field J, indeed possesses an almost product structure on the principal fibre bundle. In the later sections, we have defined trilinear frame bundle and have proved that the trilinear frame bundle is the principal bundle and have proved in Theorem 5.1 that the Jacobian map π* is the isomorphism.

Many combinatorial optimization problems can be expressed in terms of zero-one linear programs. For the maximum clique problem the so-called edge reformulation is applied most commonly. Two less frequently used LP equivalents are the independent set and edge covering set reformulations. The number of the constraints (as a function of the number of vertices of the ground graph) is asymptotically quadratic in the edge and the edge covering set LP reformulations and it is exponential in the independent set reformulation, respectively. F. D. Croce and R. Tadei proposed an approach in which the number of the constraints is equal to the number of the vertices. In this paper we are looking for possible tighter variants of these linear programs.

We introduce the directional short-time Fourier transform for which we prove a new Plancherel’s formula. We also prove for this transform several uncertainty principles as Heisenberg inequalities, logarithmic uncertainty principle, Faris–Price uncertainty principles and Donoho–Stark’s uncertainty principles.

We deﬁne the extended beta family of distributions to generalize the beta generator pioneered by Eugene et al. . This paper is cited in at least 970 scientiﬁc articles and extends more than ﬁfty well-known distributions. Any continuous distribution can be generalized by means of this family. The proposed family can present greater ﬂexibility to model skewed data. Some of its mathematical properties are investigated and maximum likelihood is adopted to estimate its parameters. Further, for different parameter settings and sample sizes, some simulations are conducted. The superiority of the proposed family is illustrated by means of two real data sets.
We present the sufficient condition for a classical two-class problem from Fisher discriminant analysis has a solution. Actually, the solution was presented up to our knowledge with a necessary condition only. We use an extended Cauchy–Schwarz inequality as a tool.

Based on this inequality and known results for the Lusin area integral , the author establishes the strong-type and weak-type estimates for the Littlewood–Paley–Stein function on . In this article, the author also introduces a class of Morrey spaces associated with the Schrödinger operator on . By using some pointwise estimates of the kernels related to the nonnegative potential V, the author establishes the boundedness properties of the operator acting on the Morrey spaces for an appropriate choice of . It can be shown that the same conclusions hold for the operator on generalized Morrey spaces as well.
