# Erratum: Inverse nodal problem for *p*-Laplacian energy-dependent Sturm-Liouville equation

*Boundary Value Problems*
**volume 2014**, Article number: 222 (2014)

In this note, we correct some mistakes in Theorem 2.1 and Theorem 2.2 which are given in Ref. [1].

Consider the problem (1.3), (1.4) in [1].

## Theorem 2.1

[1]

*The eigenvalues*{\lambda}_{n}*of the Dirichlet problem* (1.3), (1.4) *are*

## Theorem 2.2

[1]

*For the problem* (1.3), (1.4), *the nodal point expansion satisfies*

## Proof

Let \lambda ={\lambda}_{n}; integrating (2.3) from 0 to {x}_{j}^{n}, we have

By using the estimates of eigenvalues as

we obtain the result. □
