MATH 304 Linear Algebra Lecture 16b: Euclidean structure in R
... Let v be a vector and r ∈ R. By definition, r v is a vector whose magnitude is |r | times the magnitude of v. The direction of r v coincides with that of v if r > 0. If r < 0 then the directions of r v and v are ...

... V is a vector space and let W ⊂ V be a subset. This means that W consists of some (but not necessarily all) of the vectors in V. Since V is a vector space, we know that we can add vectors in W and multiply them by scalars, but does that make W into a vector space in its own right? As we saw above wi ...

RT -symmetric Laplace operators on star graphs: real spectrum and self-adjointness
... It follows that the operator LA is self-adjoint if and only if A is a Hermitian matrix A∗ = A. In this paper we are not interested in the case where LA is self-adjoint. The spectrum of the operator LA may contain up to N isolated eigenvalues. The corresponding eigenfunction is a solution to the diff ...
