Date: 27.10.2023 (Friday) Time and Venue:  4.30-5.30 PM at the Ramanujan Hall (Transit Campus) Speaker: Dr. Manjunath Krishnapur, Department of Mathematics, IISc Bangalore   Title: Log-concavity of certain probability distributions. Abstract:  Log-concavity of a sequence (a_n^2\ge a_{n-1}a_{n+1}) or function (f(x)^2\ge f(x-h)f(x+h)) or measure (\mu(C)^2\ge \mu(A)\mu(B) if C=(A+B)/2)  gives many strong conclusions, such as its decay or `concentration’ properties. For example, the… Continue reading Log-concavity of certain probability distributions.
