数値解析・応用解析セミナー 3月7日(月) 15:30 -- 16:30 Victor Isakov (Wichita State University, USA) ``On increasing stability of the continuation for the Helmholtz equation'' <研究発表要旨> We analyse stability in the Cauchy problem for the Helmholtz equation. We give most advanced Singular Value Decomposition study of the continuation operator from an interval toward outside a circle in the two dimensional case. We show increasing stability inside a convex hull of the curve/surface with Cauchy data and remind the example of Fritz John of increasing instability outside a convex hull, and propose how to regain stability for "low frequency" part of the solution. セミナー室: 京都大学 工学部2号館 2階203号室 (応用解析学講座セミナー室) ●工学部2号館はキャンパスマップでは「京都大学本部構内 54番建物」です。 ------------------------------------------------------------- セミナー連絡先: 京都大学大学院 情報学研究科 複雑系科学専攻 磯 祐介 e-mail; iso@i.kyoto-u.ac.jp
