    Lattice-like operations and isotone projection sets

    Full text link
    By using some lattice-like operations which constitute extensions of ones introduced by M. S. Gowda, R. Sznajder and J. Tao for self-dual cones, a new perspective is gained on the subject of isotonicity of the metric projection onto the closed convex sets. The results of this paper are wide range generalizations of some results of the authors obtained for self-dual cones. The aim of the subsequent investigations is to put into evidence some closed convex sets for which the metric projection is isotonic with respect the order relation which give rise to the above mentioned lattice-like operations. The topic is related to variational inequalities where the isotonicity of the metric projection is an important technical tool. For Euclidean sublattices this approach was considered by G. Isac and respectively by H. Nishimura and E. A. Ok.Comment: Proofs of Theorem 1 and Corollary 4 have been corrected. arXiv admin note: substantial text overlap with arXiv:1210.232

    A historical phonology of Western Karaim : the process of its diversification into dialects : part 2. Supplementary data on the absolute and relative chronology of sound changes

    This article is a supplement to NĂ©meth (2015), in which the absolute and relative chronology of the 18th and 19th century Karaim sound changes was presented with the aim of reconstructing how Middle Western Karaim evolved into its two well-known Modern Western Karaim dialects. Most of the conclusions formulated in NĂ©meth (2015) are further confirmed in the present article, while a few have been slightly modified
