In addition to the typical areas of mathematical research, there are top-level categories for "All valid MSC classification codes must have at least the first-level identifier.The second-level codes are a single letter from the Latin alphabet.
It is common to see codes from one or more of these schemes on individual papers.The top-level subjects under the MSC are, grouped here by common area names that are not part of the MSC:The following outline is provided as an overview of and topical guide to academic disciplines:Mathematics encompasses a growing variety and depth of subjects over history, and comprehension requires a system to categorize and organize the many subjects into more general The following outline is provided as an overview of and topical guide to formal science:This is a glossary of terms that are or have been considered areas of study in mathematics.Alphanumerical classification scheme used by many mathematics journals
This can sometimes make it difficult to search for older works dealing with particular topics. A typical MSC subject class line on a research paper looks likeThe original classification of older items has not been changed. These codes are of the form:The second and third level of these codes are always the same - only the first level changes. Changes at the first level involved the subjects with (present) codes 03, 08, 12-20, 28, 37, 51, 58, 74, 90, 91, 92.The classification scheme used on the arXiv is chosen to reflect the papers submitted. A classification can be two, three or five digits long, depending on how many levels of the classification scheme are used.The first level is represented by a two-digit number, the second by a letter, and the third by another two-digit number. Mathematical theory of classification (IEKO) One of the main topics of scientific research, classification, is the operation consisting of distributing objects in classes or groups which are, in general, less numerous than them.
The classification of a collection of objects generally means that a list has been constructed with The #1 tool for creating Demonstrations and anything technical.Explore anything with the first computational knowledge engine.Explore thousands of free applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more.Join the initiative for modernizing math education.Walk through homework problems step-by-step from beginning to end. These represent specific areas covered by the first-level discipline. The Mathematics Subject Classification (MSC) is an alphanumerical classification scheme collaboratively produced by staff of, and based on the coverage of, the two major mathematical reviewing databases, Mathematical Reviews and Zentralblatt MATH. For example, it is not valid to use Third-level codes are the most specific, usually corresponding to a specific kind of mathematical object or a well-known problem or research area.The third-level code 99 exists in every category and means The AMS recommends that papers submitted to its journals for publication have one primary classification and one or more optional secondary classifications.

Classification means putting objects into groups (classes) based on some property they have. The second-level codes vary from discipline to discipline.For example, for differential geometry, the top-level code is In addition, the special second-level code "-" is used for specific kinds of materials. The MSC is a hierarchical scheme, with three levels of structure.
The classification of a collection of objects generally means that a list has been constructed with exactly one member from each isomorphism type among the objects, and that tools and techniques can effectively be used to identify any combinatorially given object with its unique representative in the list. For example you might classify people by eye color. For example:At the top level, 64 mathematical disciplines are labeled with a unique two-digit number. As arXiv is multidisciplinary its classification scheme does not fit entirely with the MSC, ACM or PACS classification schemes.
