Non-Commutative Arithmetic Circuits with Division
... and presence of inversion gates. Combined with Reutenauer’s theorem, this implies that the inverse of an n × n matrix cannot be computed by a formula smaller than 2Ω(n) . In circuit complexity, one keeps searching for properties that would imply that a function is hard to compute. For a polynomial f ...

... • Matrix algebra has several uses in economics as well as other fields of study. One important application of Matrices is that it enables us to handle a large system of equations. It also allows us to test for the existence of a solution to a system of equations even before we attempt solving them. ...

Integral Closure in a Finite Separable Algebraic Extension
... When K ⊆ L is a finite algebraic extension of fields, for any λ ∈ L, we define TrL/K (λ) to be trace of the K-linear map L → L given by λ: it may be computed by choosing a basis for L over K, finding the matrix of the map given by multiplication by λ, and summing the entries of the main diagonal of ...

... (2) Let i : G → G be the inverse map. Then, die : g → g is the map X $→ −X. Proof: Consider the composite G → G × G → G, g $→ (g, i(g)) $→ gi(g) = e. The composite is a constant function, so its differential is zero. But the differential of a composite is the composite of the differentials, so appyi ...

... Proof. We need to determine whether the n × n real matrices with determinant 2 form a subgroup of GL(n, R). The group operation is matrix multiplication (inherited from GL(n, R)) and the main thing that can go wrong in subgroup problems is the closure property fails (if I have two elements both in t ...
