报告内容简介:
In this talk, we will show the quantitative unique continuation property of solutions to a bi-Laplacian equation with a potential.Our key argument is to lift the original equation to that with a positive potential, then decompose the resulted fourth-order equation into a special system of two second-order equations. Based on the special system, we define a variant frequency function with weights and derive its almost monotonicity to establishing some doubling inequalities with explicit dependence on the Sobolev norm of the potential function.
