NON-MAXIMALITY OF THE THEORY OF SYMMETRIC MONOIDAL CLOSED CATEGORIES AND DEPENDENCY OF CATEGORICAL DIAGRAMS

Abstract: Some time ago we (L. Mehats, M. Spivakovsky, S. Soloviev) had shown that there exists diagram of canonical natural transformations in SMCC such that this diagram is commutative while the classical diagram of "triple dual" is still non-commutative in some model, i.e., there exists a non-trivial extension of the theory of SMCC (the theory is non-maximal, as opposed to the case of Cartesian Closed Categories studied by Dosen and Petric). Now in our recent work with Antoine El Khoury we obtained an infinite series of diagrams D_n (n\in N) such that the commutativity of D_{n+1} does not imply the commutativity of D_n. (In the proof the SMCC of semi-modules over semi-rings are used.) As a consequence the study of dependency of diagrams in SMCCs is much more important than in case of CCC. Various methods of verification of dependency are discussed in the end of the talk.

METODA PROMENA OKOLINA U REŠAVANJU PROBLEMA KOMBINATORNE I GLOBALNE OPTIMIZACIJE

Sadrzaj: Za resavanje problema kombinatorne i globalne optimizacije postoji veliki broj egzaknih i pribliznih metoda resavanja. Na predavanju ce biti izlozena jedna od pribliznih ili heuristickih metoda, Metoda promena okolina. Bice reci i o savremenim trendovima hibridizacije egzaktnih i heuristickih pristupa.


Rukovodioci Odeljenja za matematiku Matematickog instituta SANU i Opsteg matematickog seminara na Matematickom fakultetu u Beogradu, Stevan Pilipovic i Sinisa Vrecica predlazu zajednicki program rada naucnih sastanaka.

Predavanja ce se odrzavati na Matematickom Institutu (sala 2), petkom sa pocetkom u 14 casova. Odeljenje za matematiku je opsti seminar sa najduzom tradicijom u Institutu.

Svakog meseca, jedno predavanje ce biti odrzano na Matematickom Fakultetu u terminu koji ce biti posebno odredjen.

Molimo sve zainteresovane ucesnike u radu naucnih sastanaka da posebno obrate paznju na vreme odrzavanja svakog sastanka. Na Matematickom fakultetu su moguce izmene termina.

Obavestenje o programu naucnih sastanaka ce biti objavljeno na oglasnim tablama MI (Beograd), MF (Beograd), PMF (Novi Sad), PMF (Nis) i PMF (Kragujevac).
