Regional math­e­mat­i­cal cen­ter of South­ern Fed­eral Uni­ver­sity is pleased to invite you to the Sem­i­nar on analy­sis, dif­fer­en­tial equa­tions and math­e­mat­i­cal physics, which will be held on 27 Sep­tem­ber 2018 at 15:30 in the room 212.

The title of the lec­ture: Div-​Curl Sys­tem and con­se­quences. Lec­turer: Briceyda B. Delgado.

Abstract: In this talk we will recall some prop­er­ties of the non-​commutative alge­bra of quater­nions and some fun­da­men­tal prop­er­ties of the Teodor­escu trans­form, which was fun­da­men­tal for the solu­tion of the div-​curl sys­tem in star-​shaped domains.

Now we will give a weak solu­tion to the div-​curl sys­tem in bounded Lip­schitz domain in R3 [2], this allows us to con­sider more gen­eral domains with weaker topo­log­i­cal constraints.

Some appli­ca­tions of this solu­tion are to the main Vekua equa­tion and to the sta­tic Maxwell’s equa­tions with vari­able per­me­abil­ity [1].

In the con­struc­tion of the solu­tion to the div-​curl sys­tem besides of the com­po­nents oper­a­tors of the clas­si­cal Teodor­escu trans­form [1] are involved other layer poten­tial oper­a­tors related with clas­si­cal Dirich­let prob­lems [3].
