Treves a link between solvability
WebNirenberg and Treves have introduced a condition for principal-type pseudo- differential operators [14]. This condition, called Y, is imposed on the principal symbol. They showed that this condition is equivalent to local solvability in the analytic case, and is necessary in many other cases [14, 151. Beals and WebWe give a proof of the Nirenberg-Treves conjecture: that local solvability of principal type pseudodifferential operators is equivalent to condition (Psi). This condition rules out sign …

Webfrequently appear in applications. In particular, we establish a link between solvability and the dominance solvability. Under a quasiconcavity condition, any finite pairwise solvable game is shown to be dominance solvable. A two-person symmetric game is pairwise solvable if any 2 2 game generated by a pair of strategies is solvable in the ...
WebDec 14, 2024 · We present a simple criterion for solvability of lattice spin systems on the basis of graph theory and simplicial homology. The lattice systems satisfy algebras with graphical representations. It is shown that the null spaces of adjacency matrices of the graphs provide conserved quantities of the systems. Furthermore, when the graphs … WebNoun; Capability of being solved. * 1972 , Richard Y Kain, Automata Theory: Machines and Languages Many of the results listed in this table are the direct consequence of implications concerning the unsolvability or solvability of certain problems.; The condition of being solvent; ability to pay debts; solvency.
