    Abstract

    The well-posedness of an initial–boundary value problem for a model parabolic equation with two power-law degeneration lines is studied....

  3. One Version of the Theorem on Stability by the First Approximation in the Discrete-Time Case

    Abstract

    We extend an analog of the Chetaev–Malkin–Massera theorem on stability by the first approximation for differential systems to discrete-time...

  5. Effective Obstruction to Lifting Tate Classes from Positive Characteristic

    We give an algorithm that takes a smooth hypersurface over a number field and computes a p-adic approximation of the obstruction map on the Tate...
