Amanda Macone,Sait Ashinand modules over fields (vector spaces). This includes a study of matrices as they arise in linear algebra. We use at the beginning for examples and motivation spaces of functions. We feel it is a natural intuitive way of approaching the vector space concept for beginners and ties in neatly with coor

Berkay Alpay,Bariscan Cimen,Yildirim Sara (a commutative group with an exterior ring multiplication), and elsewhere, but here we organize the systems of one binary operation into one chapter and give some additional specialized results. The most general algebraic system we consider in this chapter is the monoid, a set with one associative

Nil Tekin,Aynur Özgehisms from one module to another. The coordinate morphism provides the tie between the module of morphisms and the module of . by . matrices. The collective structure of the module of morphisms is further extended through composition to produce the algebra of endomorphisms and the corresponding alge

Füsun Mayda Domaçand give examples, such as cyclotomic extensions, abelian extensions, and even non-abelian ones, leading into the study of matrix representations of the Galois group and their classifications. We shall mention a number of fundamental unsolved problems, the most notable of which is whether given a fi

Nervous System Involvement and Clinical Manifestations of COVID-19,e studies reported that CoV can be found in the brain or cerebrospinal fluid. There is stil not enough knowledge about the pathobiology of these neuroinvasive viruses, but it is important to explore the impact of CoV infections on the nervous system.
