The trace is used to define characters of group representations. Two representations A, B : G → GL(V) of a group G are equivalent (up to change of basis on V) if tr(A(g)) = tr(B(g)) for all g ∈ G. The trace also plays a central role in the distribution of quadratic forms. Lie algebra Prikaži več In linear algebra, the trace of a square matrix A, denoted tr(A), is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace is only defined for a square matrix (n × n). Prikaži več Basic properties The trace is a linear mapping. That is, A matrix and its transpose have the same trace: This follows immediately from the fact that transposing a square matrix does not affect elements … Prikaži več In general, given some linear map f : V → V (where V is a finite-dimensional vector space), we can define the trace of this map by considering the trace of a matrix representation of … Prikaži več The trace of an n × n square matrix A is defined as Expressions like tr(exp(A)), where A is a square matrix, … Prikaži več Let A be a matrix, with Then Prikaži več If A is a linear operator represented by a square matrix with real or complex entries and if λ1, ..., λn are the eigenvalues of A (listed according to their algebraic multiplicities), … Prikaži več Stochastic estimator The trace can be estimated unbiasedly by "Hutchinson's trick": Given any matrix Prikaži več the good guys 77 inch oled smart tv
