Bachelor's degreeA bachelor's degree (from Middle Latin baccalaureus) or baccalaureate (from Modern Latin baccalaureatus) is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc).
Produit tensoriel d'algèbresEn mathématique, le produit tensoriel de deux algèbres est une nouvelle algèbre. Soit un anneau commutatif. Soient deux -algèbres (non nécessairement commutatives). Leur structure de -algèbres est donnée par deux morphismes et . On peut les considérer comme des -modules et construire le produit tensoriel . Lorsque et commutent à , c'est-à-dire lorsque pour tout , on a et , on montre qu'il existe une loi de composition interne sur ce produit tensoriel uniquement déterminée par la règle pour tous et .
Statistical data typeIn statistics, groups of individual data points may be classified as belonging to any of various statistical data types, e.g. categorical ("red", "blue", "green"), real number (1.68, -5, 1.7e+6), odd number (1,3,5) etc. The data type is a fundamental component of the semantic content of the variable, and controls which sorts of probability distributions can logically be used to describe the variable, the permissible operations on the variable, the type of regression analysis used to predict the variable, etc.
Multivariable calculusMultivariable calculus (also known as multivariate calculus) is the extension of calculus in one variable to calculus with functions of several variables: the differentiation and integration of functions involving multiple variables (multivariate), rather than just one. Multivariable calculus may be thought of as an elementary part of advanced calculus. For advanced calculus, see calculus on Euclidean space. The special case of calculus in three dimensional space is often called vector calculus.
