SUMMARY:Семинар "Алгебра и логика"
DESCRIPTION:На 29 октомври 2021 г. (петък) от 17:00 часа ще се проведе дистанционно заседание на семинара по „Алгебра и логика”. \nДоклад на тема \nTropical Geometry and the Commutative Algebra of Semirings\nще изнесе Kalina Mincheva (Tulane University\, New Orleans\, USA). \nАбстракт. \n\nTropical geometry provides a new set of purely combinatorial tools\, which has been used to approach classical problems. In tropical geometry most algebraic computations are done on the classical side – using the algebra of the original variety. The theory developed so far has explored the geometric aspect of tropical varieties as opposed to the underlying (semiring) algebra and there are still many commutative algebra tools and notions without a tropical analogue. In the recent years\, there has been a lot of effort dedicated to developing the necessary tools for commutative algebra using different frameworks\, among which prime congruences\, tropical ideals\, tropical schemes. These approaches allows for the exploration of the properties of tropicalized spaces without tying them up to the original varieties and working with geometric structures inherently defined in characteristic one (that is\, additively idempotent) semifields. In this talk we explore the relationship between tropical ideals and congruences and what they remember about the geometry of a tropical variety. \n\nСеминарът ще се проведе посредством платформата Zoom и всеки желаещ може да се присъедини като последва линка: \nhttps://us02web.zoom.us/j/85137375021?pwd=RE5QczdFTE1xL1R6MnI2b1lkcGczQT09 \nTopic: Онлайн семинар на секция “Алгебра и логика”\nTime: Oct 29\, 2021 05:00 PM Sofia\nMeeting ID: 851 3737 5021\nPasscode: 035647 \nОт секция „Алгебра и логика” на ИМИ – БАН\nhttp://www.math.bas.bg/algebra/seminarAiL/\n============================== =====================
