Under the map Υ ◦ Φ, the (A, S)-involutions are in bijection with A-compatible ornaments such that (i) there are only 1-cycles and 2-cycles; (ii) any 2-cycle has vertices of

In 1992 Greither [10] refined the method of Rubin and used the Euler system of cyclotomic units to give an elementary (but technical) proof of the second version of the Main

If we are sloppy in the distinction of Chomp and Chomp o , it will be clear which is meant: if the poset has a smallest element and the game is supposed to last longer than one

All three problems (1*, 2*.1 2*.2) are open; there are conjectures which would provide complete answers to these problems and some partial results supporting these conjectures

In the simplest case, when all fluid particles cross boundary, and there are no closed stream lines, the function Ω (ξ 1 , ξ 2 ) is determined from the inflow conditions on the

Based on sequential numerical results [28], Klawonn and Pavarino showed that the number of GMRES [39] iterations for the two-level additive Schwarz methods for symmetric

In this article, using the sub-supersolution method and Rabinowitz- type global bifurcation theory, we prove some results on existence, uniqueness and multiplicity of positive

Our goal in this short note is to give a quick proof of a stronger result, which immediately generalizes to partially resolve a conjecture of Gica and Luca on equation (1)..
