We will give an introduction into the notions of the Spectral Gap and Logarithmic Sobolev Inequality, and display some of their applications. More precisely, we will discuss some criteria, namely the tensorization property, and the criteria of Bakry-Emery and Holley-Stroock. Applications discussed will involve hyper-contractivity of the overdamped Langevin equation, the construction of singular products in stochastic partial differential equations, and a selected application in stochastic homogenization.
All this, as usual, as time permits.
