Entrepreneurship in Transition Economies the geometrical notion of the length of a vector. In Euclidean geometry, the angle between two vectors is specified by their dot product, which is itself formalized by the abstract concept of an inner product. Inner products and norms lie at the heart of linear (and nonlinear) analysis, in both fin

Marc Helmold,Tracy Dathe,Isabel Datheectrical networks. Both physical problems fit into a common, and surprisingly general, mathematical framework. The physical laws of equilibrium mechanics and circuits lead to linear algebraic systems whose coefficient matrix is of positive (semi-)definite Gram form. The positive definite cases corre

Entrepreneurship in a European Perspectiveor developing the fundamentals of linear algebra. In its initial form, matrices and vectors were the primary focus of our study, but the theory was developed in a sufficiently general and abstract form that it can be immediately used in many other useful situations — particularly infinitedimensional

Basic Principles of Entrepreneurship,s, and structures, all modeled by linear systems of algebraic equations. It is now time to set the universe in motion. In general, a (continuous) dynamical system refers to the (differential) equations governing the time-varying motion of a physical system, be it mechanical, electrical, chemical, fl

Postmodern Social Justice in Action,ential equations. Such systems, whose unvarying equilibria were the subject of Chapter 6, include the dynamical motions of mass–spring chains and structures, and the time–varying voltages and currents in simple electrical circuits. Dynamics of continuous media, including fluids, solids, and gases, a
