We extend Henry Poincarés normal form theory for autonomous differential equations x=f(x) to nonautonomous differential equations x=f(t, x). Poincarés nonresonance condition λj−∑ni=1 ℓiλi≠0 for eigenvalues is generalized to Nike Air Max Canada Price the new nonresonance condition λj∩∑ni=1 ℓiλi= for spectral intervals.
minimum dominating set of queens is one of the typical programming exercises of a first year’s computer science course. However, little work has been published on the complexity of this problem. We analyse here several algorithms and show that advanced algorithmic techniques may dramatically speed up solving this problem.
We conduct a field experiment on tax compliance, focusing on newly founded firms. As a novelty the effect of tax authorities’ supervision on timely tax payments is examined. Interestingly, results show no positive overall effect of close supervision on tax compliance.
Another, more elementary Air Max 97 Milan proof is given Air Max 97 of Proposition 2.3 in a recent paper by Dietrich Burde. This proposition says that n × n matrices A and X over an algebraically closed field K of characteristic zero satisfying the equality in the title of this paper can be simultaneously triangularized. The proposed proof is based on the Shemesh criterion for two matrices to have a common eigenvector.
