Tytuł:: Minimality in asymmetry classes
Autorzy:: Wiernowolski, Michał
Powiązania:: https://bibliotekanauki.pl/articles/1219818.pdf

Opis:: We examine minimality in asymmetry classes of convex compact sets with respect to inclusion. We prove that each class has a minimal element. Moreover, we show there is a connection between asymmetry classes and the Rådström-Hörmander lattice. This is used to present an alternative solution to the problem of minimality posed by G. Ewald and G. C. Shephard in [4].

Tytuł:: Romanian and Japanese Name Truncations
Autorzy:: Avram, Andrei A.
Powiązania:: https://bibliotekanauki.pl/articles/504734.pdf
Data publikacji:: 2016
Wydawca:: Komisja Nauk Filologicznych Polskiej Akademii Nauk, Oddział we Wrocławiu
Tematy:: name truncation
syllable
bimoraic foot
prosodic minimality
derived word
Opis:: This paper looks into the structural properties of both Romanian and Japanese truncated names. Name truncation is considered to be a word-formation process and is analyzed from the perspective of Prosodic Morphology (McCarthy & Prince 1995, 1998; Booij 2005; Downing 2006). A contrastive analysis of the morphological and phonological structure of truncated names in both Romanian and Japanese shows that they are subject to strict prosodic requirements. Thus, linguistically significant generalizations and constraints on the makeup of truncated names can only be formulated in terms of moras, syllables and feet. Also discussed is the relation between name truncation and prosodic minimality in the two languages.

Tytuł:: Optimality conditions and a classification of duality schemes in vector optimization
Autorzy:: El Ghali, B.
Powiązania:: https://bibliotekanauki.pl/articles/205741.pdf
Data publikacji:: 2000
Wydawca:: Polska Akademia Nauk. Instytut Badań Systemowych PAN
Tematy:: dwoistość
optymalizacja wektorowa
duality
existential solutions
minimality
vector optimization
Opis:: Vector minimization of a relation F valued in an ordered vector space under a constraint A consists in finding x[0] belongs to A, w[0] belongs to Fx[0] such that w[0] is minimal in FA. To a family of vector minimization problems minimize[x belongs to X] F(x, y), y [belongs to] Y, one associates a Lagrange relation [L(x, [xi], y[0]) = union of sets y belongs to Y(F(x, y)-xi(y)+(y[0]))] where [xi] belongs to an arbitrary class [Xi] of mappings. For this type of problem, there exist several notions of solutions. Some useful characterizations of existential solutions are established and, consequently, some necessary conditions of optimality are derived. One result of intermediate duality is proved with the aid of the scalarization theory. Existence theorems for existential solutions are given and a comparison of several exact duality schemes is established, more precisely in the convex case it is shown that the majority of exact duality schemes can be obtained from one result of S. Dolecki and C. Malivert.

Opis:: We review the realization theory of polynomial (transfer function) matrices via 'pure' generalized state space system models. The concept of an irreducible-at-infinity generalized state space realization of a polynomial matrix is defined and the mechanism of the 'cancellations' of 'decoupling zeros at infinity' is closely examined. The difference between the concepts of irreducibility and minimality of generalized state space realizations of polynomial (transfer function) matrices is pointed out and the associated concepts of dynamic and non-dynamic variables appearing in generalized state space realizations are also examined.
