• ### Linear Algebra Done Right_ Second Edition

You can teach a course that will give their students exposure to linear algebra. In their first brush with the topic, your students can work with the Euclidean space and the matrix. In contrast, this course will emphasize the abstract vector spaces and linear maps. Bold title of this book deserves an explanation. Almost all linear algebra books use determinants to prove that each linear op-erator on a finite dimensional vector space has a complex eigenvalue.

• ### Đề tài " On the complexity of algebraic numbers I. Expansions in integer bases "

Let b ≥ 2 be an integer. We prove that the b-ary expansion of every irrational algebraic number cannot have low complexity. Furthermore, we establish that irrational morphic numbers are transcendental, for a wide class of morphisms. In particular, irrational automatic numbers are transcendental. Our main tool is a new, combinatorial transcendence criterion. 1. Introduction Let b ≥ 2 be an integer. The b-ary expansion of every rational number is eventually periodic, but what can be said about the b-ary expansion of an irrational algebraic number? ...

• ### Lecture Linear algebra: Chapter 0 - TS. Đặng Văn Vinh

Lecture "Linear algebra - Chapter 0: Complex Numbers" provides learners with the knowledge: The standard form, the trigonometric form, the exponential form, the Power of complex numbers, the Roots of complex numbers, the Fundamental Theorem of Algebra. Invite you to refer to the disclosures.

• ### Elementary Linear Algebra

This is an introduction to linear algebra. The main part of the book features row operations and everything is done in terms of the row reduced echelon form and specific algorithms. At the end, the more abstract notions of vector spaces and linear transformations on vector spaces are presented. This is intended to be a first course in linear algebra for students who are sophomores or juniors who have had a course in one variable calculus and a reasonable background in college algebra.

• ### Complex Functions Examples c-9 The Argument Principle and Many-valued Functions

This is the ninth book containing examples from the Theory of Complex Functions. We shall here treat the important Argument Principle, which e.g. is applied in connection with Criteria of Stability in Cybernetics. Finally, we shall also consider the Many-valued functions and their pitfalls. Even if I have tried to be careful about this text, it is impossible to avoid errors, in particular in the first edition. It is my hope that the reader will show some understanding of my situation.

• ### Algebra (Đại số)

This Lecture on Algebra is written for students of Advanced Training Programs of Mechatronics (from California State University –CSU Chico) and Material Science (from University of Illinois- UIUC). When preparing the manuscript of this lecture, we have to combine the two syllabuses of two courses on Algebra of the two programs (Math 031 of CSU Chico and Math 225 of UIUC). There are some differences between the two syllabuses, e.g.

• ### Mechatronic Systems, Applications

Mechatronics, the synergistic blend of mechanics, electronics, and computer science, has evolved over the past twenty-five years, leading to a novel stage of engineering design. By integrating the best design practices with the most advanced technologies, mechatronics aims at realizing highquality products, guaranteeing, at the same time, a substantial reduction of time and costs of manufacturing.

• ### Discrete Event Simulations

Considered by many authors as a technique for modelling stochastic, dynamic and discretely evolving systems, this technique has gained widespread acceptance among the practitioners who want to represent and improve complex systems. Since DES is a technique applied in incredibly different areas, this book reflects many different points of view about DES, thus, all authors describe how it is understood and applied within their context of work, providing an extensive understanding of what DES is.

• ### Mathematical Tools for Physics

I wrote this text for a one semester course at the sophomore-junior level. Our experience with students taking our junior physics courses is that even if they’ve had the mathematical prerequisites, they usually need more experience using the mathematics to handle it efficiently and to possess usable intuition about the processes involved. If you’ve seen infinite series in a calculus course, you may have no idea that they’re good for anything.

• ### Caculus

Calculus isn’t a hard subject. Algebra is hard. I still remem- ber my encounter with algebra. It was my ﬁrst taste of abstraction in mathematics, and it gave me quite a few black eyes and bloody noses. Geometry is hard. For most peo- ple, geometry is the ﬁrst time they have to do proofs using formal, ax- iomatic reasoning.

• ### Đề tài " Quiver varieties and tanalogs of q-characters of quantum affine algebras "

We consider a specialization of an untwisted quantum aﬃne algebra of type ADE at a nonzero complex number, which may or may not be a root of unity. The Grothendieck ring of its ﬁnite dimensional representations has two bases, simple modules and standard modules. We identify entries of the transition matrix with special values of “computable” polynomials, similar to Kazhdan-Lusztig polynomials. At the same time we “compute” q-characters for all simple modules. The result is based on “computations” of Betti numbers of graded/cyclic quiver varieties.

• ### Đề tài " Hypersurface complements, Milnor fibers and higher homotopy groups of arrangments "

The interplay between geometry and topology on complex algebraic varieties is a classical theme that goes back to Lefschetz [L] and Zariski [Z] and is always present on the scene; see for instance the work by Libgober [Li]. In this paper we study complements of hypersurfaces, with special attention to the case of hyperplane arrangements as discussed in Orlik-Terao’s book [OT1]. Theorem 1 expresses the degree of the gradient map associated to any homogeneous polynomial h as the number of n-cells that have to be added to a generic hyperplane section D(h) ∩ H to obtain the complement in...

• ### Đề tài " Deligne’s conjecture on 1-motives "

We reformulate a conjecture of Deligne on 1-motives by using the integral weight ﬁltration of Gillet and Soul´ on cohomology, and prove it. This implies e the original conjecture up to isogeny. If the degree of cohomology is at most two, we can prove the conjecture for the Hodge realization without isogeny, and even for 1-motives with torsion. j Let X be a complex algebraic variety. We denote by H(1) (X, Z) the maximal mixed Hodge structure of type {(0, 0), (0, 1), (1, 0), (1, 1)} contained in j j H j (X, Z). Let H(1) (X, Z)fr...

• ### Đề tài " On the periods of motives with complex multiplication and a conjecture of GrossDeligne "

We prove that the existence of an automorphism of ﬁnite order on a Q-variety X implies the existence of algebraic linear relations between the logarithm of certain periods of X and the logarithm of special values of the Γ-function. This implies that a slight variation of results by Anderson, Colmez and Gross on the periods of CM abelian varieties is valid for a larger class of CM motives. In particular, we prove a weak form of the period conjecture of Gross-Deligne [11, p. 205]1 .

• ### Đề tài " Geometric Langlands duality and representations of algebraic groups over commutative rings "

In this paper we give a geometric version of the Satake isomorphism [Sat]. As such, it can be viewed as a ﬁrst step in the geometric Langlands program. The connected complex reductive groups have a combinatorial classiﬁcation by their root data. In the root datum the roots and the co-roots appear in a symmetric manner and so the connected reductive algebraic groups come ˇ in pairs.
