Commutativity of the exponential spectrum

This paragraph is devoted to a quick review of some of the principal facts concerning Fourier and Fourier-Stieltjes series, measures, and convolutions, which

Extension of invertible rows to the principal component An interesting connection between reducibility and extension of rows to invert- ible matrices (resp. to matrices in the

Also an example of a non-minimal dynamical system, with the enveloping semigroup Σ, for which the set of all continuous elements of Σ is not equal to the topological center of Σ,

The maximal regular ideals of ~ are in correspondence with the points of G; the functions belonging to such an ideal are exactly those whose Fourier transforms

The low pressure coolant injection mode of the residual heat removal system provides makeup water to the reactor vessel for core cooling under loss of coolant accident conditions.

Important subgroups { Φ � 2s+1 } are introduced and results are proved for these groups (Lemma 5.3 and Theorem 5.4) that play a crucial role in finding the dimension and coordinates

As the number of isomorphism classes of such curves is infinite, we obtain infinitely many conjugacy classes of de Jonquières involutions in the Cremona group.. (In fact, there

With each such a we associate the braid which is the union of the strings of β starting at a and the strings obtained by shrinking the tubes corresponding to the interior components
