Additionally, we present an example demonstrating that Ehrhard symmetrization fails to decrease for the anisotropic Gaussian perimeter and introduce a new inequality that includes an error term. This new inequality, in particular, provides a clue to a uniqueness result for the Ehrhard measure within the class of anisotropic Gaussian measures. Our final result, a collaboration with Sean McCurdy, expands the class of measures to which the previous uniqueness result applies.application/pdfen-USCC BYAnisotropic Gaussian Isoperimetric InequalityAnisotropic Gaussian MeasuresEhrhard SymmetrizationGaussian Isoperimetric InequalityIsoperimetric InequalityMathematicsMathematicsThesis
