I think my question is clear from pictures. Pictures are output and its latex code .

  • Should the location Here also be covered by the left brace? – Werner Jan 29 '18 at 05:07
  • No it is outside of brace. Actually the upper term is equal to the brace term, but since the brace-term is too long I have to write them in two separate lines @Werner – Red shoes Jan 29 '18 at 05:19
  • Please avoid posting code in the form of images. Rather post the code itself. – Werner Jan 29 '18 at 06:01
  • Are there two different inner products (one with parentheses and bar, one with angle brackets and comma)? – egreg Jan 29 '18 at 09:05

You should avoid eqnarray and use the proper math notation using cases:

enter image description here

\documentclass{article}

\usepackage{amsmath}

\begin{document}

\begin{align*}
  & \mathrm{d}^2 g(F(\bar{x}) \mid \lambda) (\nabla F(\bar{x}) \omega) \\
  & \qquad = \begin{cases}
    \mathrm{d}^2 g(F(\bar{x})) (\nabla F(\bar{x}) \omega 
      & \text{if $\mathrm{d} g(F(\bar{x})) (\nabla F(\bar{x})) \omega = \langle \lambda, \nabla F(\bar{x}) \omega \rangle$} \\
    \infty & \text{otherwise}
  \end{cases}
\end{align*}

\end{document}
