ATA FORECASTING METHOD AS A BENCHMARK

by

Prof. Dr. Güçkan YAPAR, Department of Statistics, Faculty of Science, DEU, İzmir Date: December 13, 2023, Wednesday Time: 15:00 Place: Classroom B256, Department of Mathematics, Faculty of Science, DEU, İzmir.

Abstract: ATA forecasting method is a new method which is proposed as an alternative to basic forecasting method exponential smoothing (ES) and ARIMA. Although Ata method is structurally similar to the ES method but it is completely different in content. Ata method is simple, fast and more accurate than its alternatives. Ata method has taken its place in the literature by proving its success with its forecasting performance in M-competition data sets.

On rings whose cyclic modules have cyclic injective hulls

by

Prof. Dr. Christian Lomp, Department of Mathematics, University of Porto in Porto, Portugal. Date: 19th of April 2023, Wednesday. Time: 11:00. Place: Online/Microsoft Teams- Meeting ID: 351 128 968 15 Passcode: Gy4n4B

Abstract: In 1964, Barbara Osofsky proved in her PhD thesis that a ring whose cyclic modules are injective is semisimple Artinian. William Cadwell in his PhD thesis from 1966 studied when injective hulls of cyclic modules are cyclic and termed them hypercyclic rings. He characterised left perfect left hypercyclic rings as well as commutative local hypercyclic rings. In this talk we will revise the literature on rings whose cyclic modules have cyclic injective hulls and present some more recent results, obtained jointly with Mohamed Yousif and Yiqiang Zhou.

Almost Split Sequences

by

Fatma Kaynarca, Afyon Kocatepe University.
Date: 15th of November, 2022, Tuesday, Time: 13.00 – 14.00.
Place: Online-Sakai-Graduate Meetings

Abstract: Almost split sequences arose from an attempt to understand the morphisms lying in the radical of a module category are minimal non-split short exact sequences. This sequences were introduced by Maurice Auslander and Idun Reitenin 1974-1975 and have become a central tool in the theory of representations of finite dimensional algebras. We start our discussion in seminar with a short description of the radical of a module category. Then we will define and study irreducible morphisms, almost split morphisms, minimal morphisms, almost split sequences and also give some characterizations of these notions.
