In this note, we calculate all the basic invariants of the number field K = Q(3 √ 5, ω), where ω = (−1 + √ −3)/2 is a primitive cube root of unity. Here is the notation for the fields and Galois groups to be used. Let

The quintuple identity has a long history and, as Berndt [5] points out, it is difficult to assign priority to it. It seems that a proof of the identity was first published in H. A. Schwartz’s book in 1893 [19]. Watson gave a proof in 1929 in his work on the RogersRamanujan continued fractions [20]. Since then, various proofs have appeared. To name a few, Carlitz and Subbarao gave a simple proo...

Hall-Littlewood functions indexed by rectangular partitions, specialized at primitive roots of unity, can be expressed as plethysms. We propose a combinatorial proof of this formula using Schilling’s bijection between ribbon tableaux and ribbon rigged configurations.

We must mention that the assumption that we are dealing with a Cartan matrix of finite type and a root of unity appears only at the very end (see Chapter 4). We need these assumptions in order to compare our representations with the conventional definition of the category C. All previous results are valid in more general assumptions. In particular a Cartan matrix could be arbitrary and a deform...

In this paper, a look-up table control strategy derived from a fuzzy logic controller is developed for output regulation of a SISO linear plant with delay subject to load changes and transfer between different operating points. The strategy considers an off-line trained look-up table for rejection of an unity load step change and another one trained for unity reference step tracking combined in...

The subject of this thesis is quantum groups and quantum algebras at a root of unity. After an introductory chapter, I set up my notation in chapter 2. The rest of the thesis is presented in three parts. In part I, quantum matrix groups and quantum enveloping algebras are discussed. In chapter 3, I present two well-known 2 × 2 matrix quantum groups, including their coaction on the quantum plane...

because of using principles such as principality, unity, gradation of existence and concomitance between existence and unity, along with an exhaustive understanding of ibn sina's philosophical principle about our knowledge of unity and multiplicity, mulla sadra believed new philosophical-aesthetical principles such as principality, unity and gradation of beauty, though he didn't use t...

unity is one of the most important social issues in the holy religion of islam. unity makes possible entanglement from dependencies, success in settling social issues, and firmness in confronting conspiracies and invasions. since islam is a religion of kindness and brotherhood, it invites its followers to engage in being united, which will, however, never be achieved without resolving conflicts...

Mathematicians often speak of the unity of their subject. Such a unity from the 19th century origins in the history of linear ordinary differential equations, especially those closely connected with elliptic and modular functions. It is concerned with the impact of group theoretical and geometrical ideas upon the problem of understanding the nature of the solutions to a differential equation (s...
