SUMMARY:Семинар по диференциални уравнения
DESCRIPTION:На 28.06.2019 г. от 11:00 в зала 478 на ИМИ ще се състои поредната сбирка на семинара по Диференциални уравнения с докладчик Col. Prof. Chhanda Samanta\, Virginia Military Institute\, USA\nна тема:\nA GENERALIZED MASS FORMULA FOR STRANGE AND NON-STRANGE NUCLEI\nРезюме. In 1953 a strange nucleus called “Hypernucleus” was first discovered that contains a hyperon in addition to neutrons and protons. While neutrons and protons are made of up and down quarks\, hyperons are made of different combinations of up\, down and strange quarks. Since its first discovery\, about 50 different strange-nuclei have been found with different “strangeness”. In March 2010\, a strange anti-hypernucleus called\, anti-hypertriton was discovered at Brookhaven National Laboratory\, USA that gave a glimpse of the ‘hyper anti-world’ and extended the two dimensional nuclear chart to a three-dimensional one. It is difficult to measure the mass of the hypernuclei as they are very short-lived. A generalized mass formula has been formulated by us that treats strange nuclei on the same footing as the non-strange normal nuclei. It reproduces available experimental data on hypernuclei with different strangeness\, and predicts masses of the unknown ones. It also suggests possible existence of exotic strange nuclei without any neutrons and protons. This mathematical equation is currently being used as an input to estimate the production possibility of different hypernuclei and their effects in heavy-ion collision experiments.\nСекция “Диференциални уравнения и математическа физика”

DESCRIPTION:На 28.06.2019 г. от 12:00 в зала 478 на ИМИ ще се състои поредната сбирка на семинара по Диференциални уравнения с докладчик Col. Prof. Dimple Chalishajar\, Virginia Military Institute\, USA\nна тема:\nEXACT AND TRAJECTORY CONTROLLABILITY OF NONLINEAR AND FRACTIONAL ORDER SYSTEMS: A THEORETICAL AND AN ANALYTICAL APPROACH\nРезюме. Study of nonlinear systems is important since most of the practical systems are nonlinear in nature. There are different notions of controllability like complete controllability\, approximate controllability\, exact controllability\, partial exact controllability\, null controllability\, local controllability\, etc. A current notion of controllability namely Trajectory controllability (T – controllability) has been introduced as a new direction in the field of control theory. We have discussed T- controllability of the first and second order nonlinear integro-differential system by using theory of monotone operators and tools of cosine operators. We also study an exact controllability of a nonlinear system without compactness of the semigroup or cosine operator. Results are obtained numerically also to justify the theory. Examples are given to illustrate the theory time to time.\n\nСекция “Диференциални уравнения и математическа физика”
