... effective-metric Lagrangians would be expected to lead to similar results when the space-projection component of the medium’s four-velocity vanishes, and this is indeed the case. The Abraham and Minkowski momentum conservation equations describe the same situation and lead to identical results in a ...

III.3 Momentum balance: Euler and Navier–Stokes equations
... lemma—, these two tensors are simply opposite to each other. ∗ Building on the previous remark, the absence of shear stress defining a perfect fluid can be reformulated as a condition of the momentum flux tensor: A perfect fluid is a fluid at each point of which one can find a local velocity, such t ...

Some algebraic properties of differential operators
... Remark 4.2: Let A ∈ Mat× K((∂ −1 )), and denote by A* its adjoint matrix. Then det A = (−1)d(A) det A∗ . Indeed, if A = ET, where E is product of elementary matrices and T is upper triangular, then A* = T*E* and, clearly, det E ∗ = det E, while det T ∗ = (−1)d(A) det T . However, in T general, det ...

Convergence of the solution of a nonsymmetric matrix Riccati
... For any matrices A, B ∈ Rm×n , we write A ≥ B(A > B) if aij ≥ bij (aij > bij ) for all i, j. We can then define positive matrices, nonnegative matrices, etc. The spectrum of a square matrix A will be denoted by σ(A). The open left halfplane, the open right half-plane, the closed left half-plane and ...
