Heisenberg群上infinite dimensional Hörmander型生成元的对数Sobolev不等式

Logarithmic Sobolev inequalities for infinite dimensional Hörmander type generators on the Heisenberg group

James Inglis, Ioannis Papageorgiou

摘要:

海森堡群是最简单的次黎曼群之一,在其中我们可以定义非椭圆型的霍曼德型生成元。然后,我们可以考虑与这些生成元相关的强制不等式。证明了Heisenberg群的无穷乘积上具有二次相互作用势的一类非平凡Gibbs测度满足对数Sobolev不等式.

英文摘要:

The Heisenberg group is one of the simplest sub-Riemannian settings in which we can define non-elliptic Hörmander type generators. We can then consider coercive inequalities associated to such generators. We prove that a certain class of nontrivial Gibbs measures with quadratic interaction potential on an infinite product of Heisenberg groups satisfy logarithmic Sobolev inequalities.
