The next meeting of the Differential Equations Seminar will be held on February 11, 2020, at 2:00 p.m. in Room 478 of IMI-BAS. Dr. Mirko Tarulli, will deliver a lecture on: DECAY AND SCATTERING IN ENERGY SPACE FOR THE SOLUTION OF GENERALIZED HARTREE EQUATION Abstract. We prove decay with respect some Lebesgue norms for a class of Schrödinger equations with non-local nonlinearities by showing new Morawetz inequalities and estimates. As a straightforward product we obtain large-data scattering in the energy space for the solutions to the defocusing generalized Hartre equations with mass-energy intercritical nonlinearities in any space dimensions.

The next meeting of the Differential Equations Seminar will be held on December 9, 2019, at 2:00 p.m. in Room 478 of IMI-BAS. Prof. Nicola Visciglia (University of Pisa), will deliver a lecture on: GROWTH PHENOMENA FOR DISPERSIVE EQUATIONS Abstract. We present a series of joint works with N. Tzvetkov. We shall discuss the growth of Sobolev norms in the periodic setting and the growth of moments in the Euclidean setting. In this last case we also get the precise asymptotic behavior for large times.

On June 28, 2019, at 12:00 a.m. in Room 478 of IMI, the next meeting of the Differential Equations Seminar will be held. Col. Prof. Dimple Chalishajar, Virginia Military Institute, USA, will deliver a lecture on: EXACT AND TRAJECTORY CONTROLLABILITY OF NONLINEAR AND FRACTIONAL ORDER SYSTEMS: A THEORETICAL AND AN ANALYTICAL APPROACH Abstract. 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 [...]
On June 28, 2019, at 11:00 a.m. in Room 478 of IMI, the next meeting of the Differential Equations Seminar will be held. Col. Prof. Chhanda Samanta, Virginia Military Institute, USA, will deliver a lecture on: A GENERALIZED MASS FORMULA FOR STRANGE AND NON-STRANGE NUCLEI Abstract. 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 [...]
