Matrix management is an organizational structure in which some individuals report to more than one supervisor or leader—relationships described as solid line or dotted line reporting. More broadly, it may also describe the management of cross-functional, cross-business groups and other work models that do not maintain strict vertical business ...
t. e. In strategic planning and strategic management, SWOT analysis (also known as the SWOT matrix, TOWS, WOTS, WOTS-UP, and situational analysis) [1] is a decision-making technique that identifies the strengths, weaknesses, opportunities, and threats of an organization or project. SWOT analysis evaluates the strategic position of organizations ...
Diagonally dominant matrix. In mathematics, a square matrix is said to be diagonally dominant if, for every row of the matrix, the magnitude of the diagonal entry in a row is greater than or equal to the sum of the magnitudes of all the other (off-diagonal) entries in that row. More precisely, the matrix is diagonally dominant if.
Weak formulations are important tools for the analysis of mathematical equations that permit the transfer of concepts of linear algebra to solve problems in other fields such as partial differential equations. In a weak formulation, equations or conditions are no longer required to hold absolutely (and this is not even well defined) and has ...
Stationary process. In mathematics and statistics, a stationary process (or a strict/strictly stationary process or strong/strongly stationary process) is a stochastic process whose unconditional joint probability distribution does not change when shifted in time. Consequently, parameters such as mean and variance also do not change over time.
The weak duality theorem says that, for each feasible solution x of the primal and each feasible solution y of the dual: c T x ≤ b T y. In other words, the objective value in each feasible solution of the dual is an upper-bound on the objective value of the primal, and objective value in each feasible solution of the primal is a lower-bound ...
The growth–share matrix[2] (aka the product portfolio matrix, [3] Boston Box, BCG-matrix, Boston matrix, Boston Consulting Group analysis, portfolio diagram) is a chart created in a collaborative effort by BCG employees: Alan Zakon first sketched it and then, together with his colleagues, refined it.

Beyond the Standard Model. In particle physics, CP violation is a violation of CP-symmetry (or charge conjugation parity symmetry): the combination of C-symmetry (charge conjugation symmetry) and P-symmetry (parity symmetry). CP-symmetry states that the laws of physics should be the same if a particle is interchanged with its antiparticle (C ...
