Regular Semigroups with Quasi-Ideal Orthodox Transversals

  • Xiangjun Kong


We give some simple algebraic conditions on the coefficients of a boundary value problem for a differential equations of Ventcel type, depending on a spectral parameter, which guarantee the existence, uniqueness of a solution and coerciveness estimate, for a spectral parameter lying in some sector.
