The objective function considered not is necessarily convex and satisfies the property of Kurdyka- Lojasiewicz around by their generalized critical points. More specifically, we will show that any limited sequence, generated from MPP, converge the a generalized critical point. / Neste trabalho, baseado em [1, 18], estudamos a convergência do método do ponto proximal (MPP) regularizado por uma quase-distância aplicado a um problema de otimização. A função objetivo considerada não é necessariamente convexa e satisfaz a propriedade de Kurdyka-Lojasiewicz ao redor de seus pontos críticos generalizados. Mais precisamente, mostraremos que qualquer sequência limitada, gerada pelo MPP, converge a um ponto crítico generalizado.
