  • Antiplane Axisymmetric Creep Deformation of Incompressible Medium 

    Firsov, Sergey N.; Prokudin, Aleksandr N.; Фирсов, Сергей Н.; Прокудин, Александр Н. (Сибирский федеральный университет. Siberian Federal University., 2015-11)
    Flow of incompressible medium under varying gradient of pressure is considered. It is assumed that medium exhibits nonlinear elastic and creep behavior. The theory of large strains based on transport equations for the ...

  • On the Structure of the Classical Discriminant 

    Mikhalkin, Evgeny N.; Tsikh, Avgust К.; Михалкин, Евгений Н.; Цих, Август К. (Сибирский федеральный университет. Siberian Federal University., 2015-11)
    Consider a general polynomial of degree n with variable coefficients. It is known that the Newton polytope of its discriminant is combinatorially equivalent to an (n􀀀1)-dimensional cube. We show that two facets of this ...
