DESCRIPTION:Higher-order Cheeger inequalities for Laplacian and Steklov eig
 envalues.\n\nCheeger’s inequality is a lower bound for the Laplacian’s fir
 st eigenvalue on a manifold depending only a geometric constant called Che
 eger’s constant. I will present a higher-order Cheeger inequality for comp
 act manifold without boundaries\, giving a lower bound for higher eigenval
 ues using a natural generalisation of Cheeger’s constant. This result is a
 dapted from the proof by Lee\, Gharan and Trevissan [1] of this inequality
  for the discrete Laplacian on graphs. I will also apply their methods to 
 prove a similar inequality for Steklov eigenvalues.  \n
