Naslov predavanja: p-ELIPTIČNOST
Apstrakt: Koncept p-eliptičnosti uveden je g. 2016 kao uopštenje klasičnog pojma eliptičnosti za kompleksne matrice. Ispostavilo se da je pojam vrlo primeren za izučavanje Lp svojstava eliptičkih operatora. Cilj predavanja je objašnjenje nastanka ovog pojma, a potom i njegovu upotrebu na primerima iz teorije operatorskih polugrupa.

Naslov predavanja: COMPARATIVE STUDY ON TYPE-2 AND TYPE-3 FUZZY LOGIC INFERENCE SYSTEMS AND ITS APPLICATION IN POLYPROPYLENE BUSINESS
Apstrakt:
The polypropylene is a versatile thermoplastic resin available in a wide range of formulations for engineering applications. This research work presents a new approach to predict the quality of polypropylene in chemical plants. A model is constructed based on a large number of data collected from a renowned petrochemical plant in India and used to predict the polypropylene quality through the proposed approach. The quality of polypropylene depends on the indices like melt flow index and the xylene solubility of the product. The parameters controlling these two indices are hydrogen flow, donor flow, pressure and temperature of polymerization reactors. Using these four input and two output parameters, four Mamdani type-2 and type-3 fuzzy inference systems are constructed depending on the different membership functions of the variables. The model outcomes are then compared with the collected plant data and a sequence of statistical data analyses selects the most suitable model among them. Some sensitivity analyses with respect to some parameters are also performed to validate the proposed models. The raw materials for producing polypropylene are very much costly specially the catalyst teal. So the desired grade of PP is not achieved by the trial and error run then the production cost becomes uncontrollable. With the help of our proposed approach by controlling some parameters during the production phase, the quality of polypropylene can be improved.

Naslov predavanja: SPECIAL BOHR - SOMMERFELD GEOMETRY: TOWARD THE MODULI SPACE
Apstrakt:
As once Yuri Manin said: Mirror Symmetry is a duality between complex and symplectic geometries of Kahler manifolds. But complex geometry is rather rigid: variations of complex submanifolds of a compact Kahler manifold are finite dimensional, the same happens for stable holomorphic vector bundles over algebraic varieties etc. while symplectic geometry is rather flexible.
So if one beliefs that in some sense lagrangian submanifolds correspond to vector bundles, sheaves of whatever it should be a way how to derive some finite dimensional moduli spaces with the elements presented by certain lagrangian submanifolds. For the Calabi - Yau case one knows the way: it is called Special Lagrangian geometry, extremely popular subject during last 30 years. But this program can be applied in the case of Calabi - Yau only; one can remember a relative construction presented by D. Auroux for "open Calabi - Yau", but this program was not finished yet.
Special Bohr - Sommerfeld geometry is an attempt to construct finite dimensional moduli space for any compact simply connected algebraic variety.
Unexpectedly the SBS - story turned out to be related to the theory of Weinstein structures and Eliashberg conjectures. And the most intriguing is the fact that for the known examples these moduli spaces are itself algebraic varieties.

Naslov predavanja: ON HIGHER ORDER TENSOR SPECTRAL ANALYSIS
Apstrakt:
Classical spectral analysis has been expanded to include tensors as generalizations of matrices. But tensors are approached in various manners, through four distinct perspectives. There exist numerous generalizations of the classical eigenproblem. The aim is to present most of these varieties, offering appropriate motivations, definitions, properties, and applicative aspects for each. The main subject is the geometrical eigenproblem concerning tensors within Riemannian space.
