Involutivity of truncated microsupports
Using a result of J-M. Bony, we prove the weak involutivity of truncated microsupports. More precisely, given a sheaf F on a real manifold and k ∈ Z, if two functions vanish on SSk(F ), then so does their Poisson bracket.
متن کاملInvolutivity of Field Equations
We prove involutivity of Einstein and Einstein-Maxwell equations by calculating the Spencer cohomology of these systems. Relation with Cartan method is traced in details. Basic implications through Cartan-Kähler theory are derived.
متن کاملInvestigation of Truncated Waveguides
N.P. Lourie, D.T. Chuss, R.M. Henry, E.J. Wollack Abstract The design, fabrication, and performance of truncated circular and square waveguide cross-sections are presented. An emphasis is placed upon numerical and experimental validation of simple analytical formulae that describe the propagation properties of these structures. A test component, a 90-degree phase shifter, was fabricated and tes...
متن کاملTruncated Diierentials of Idea
In 1991 Lai, Massey and Murphy introduced the IPES (Improved Proposed Encryption Standard), later renamed IDEA (International Data Encryption Algorithm). In this paper we analyse versions of IDEA with a reduced number of rounds. We consider diierential attacks using truncated diierentials, which can be used to cryptanalyse, at least in theory, up to 3.5 rounds of IDEA. The attack on 3.5 rounds ...
