Outline of Annual Research Achievements

本年度は昨年度に引き続き、古典場の理論に現れる方程式としての非相対論的場の方程式及び半相対論的場の方程式、またこの理論に深い関連を持つ臨界型ハーディーの不等式を対象として研究を行った。非相対論的場の方程式として最単純モデルと考えられる非線型シュレディンガー方程式に対してはゲージ不変性が破綻すると時間大域解が存在しない(爆発現象)事が起こる様子を記述し、その機構を常微分方程式の見地から解明した。
また、対数型ソボレフ埋蔵(ブレジス・ガルエの不等式)と対数型グロンウォールの補題を組み合せたブレジス・ガルエの論法を、高階ソボレフノルムに繰り込み項を導入した補正高階エネルギーを定義する事に依って、従来よりも高次の冪を持った非線型シュレディンガー方程式や半相対論的場の方程式の時間大域解の存在を証明する事が出来た。
臨界型ハーディーの不等式の研究では、その基礎となるべき等式版を見出し、剰余項を明示化し、最適化函数の非存在の機構をコンパクト性の議論に依らない形で具体的に解明する事が出来た。
