Title: Continuous dependence of solutions to mixed boundary value problems for a parabolic equation Authors: Moussa Zakari Djibibe (Univ. of Lome, Togo) Kokou Tcharie (Univ. of Lome, Togo) Nikolay Iossifovich Yurchuk (Belarussian State Univ, Belarus) Abstract: We prove the continuous dependence, upon the data, of solutions to second-order parabolic equations. We study two boundary-value problems: One has a nonlocal (integral) condition and the another has a local boundary condition. The proofs are based on a priori estimate for the difference of solutions. Submitted October 16, 2007. Published February 05, 2008. Math Subject Classifications: 35K20, 35K25, 35K30.
