Geometric description of the mountain pass critical points
, 2014 In this short commentary I present the main results contained in the famous paper [P. Pucci & J. Serrin, The structure of the critical set in the mountain pass theorem, Trans. Amer. Math. Soc. 299 (1987), no. 1, 115–132].

Existence of solutions to perturbed critical biharmonic equations with Hardy potential
Electronic Journal of Differential EquationsThis article studies a perturbed critical biharmonic equation with Hardy potential. The main challenge arises from the combined effects of critical Sobolev nonlinearity and singular Hardy potential, which induce a double loss of compactness in the ...

Multiple solutions for coercive p-Laplacian equations
, 2006 We obtain multiple nonzero solutions for coercive p-Laplacian equations. In order to obtain the third nonzero solution, we use the second deformation lemma to construct the desired mountain pass ...

On Mountain Pass Type Algorithms
, 2013 We consider constructive proofs of the mountain pass lemma, the saddle point theorem and a linking type theorem. In each, an initial “path” is deformed by pushing it downhill using a (pseudo) gradient flow, and, at each step, a high point on the deformed

Mountain Passes and Saddle Points
, 2015 Variational methods find solutions of equations by considering a solution as a critical point of an appropriately chosen function. Local minima and maxima are well-known types of critical points.

Multiple solutions for a class of biharmonic equations with a nonlinearity concave at the origin
, 2011 In this paper, we investigate the existence of multiple solutions for a class of biharmonic equations where the nonlinearity involves a concave term at the origin.
