I want to remove unwanted blank page after I make too long footnote

As I write down my title, I want to remove unwanted blank page between first page and third page.

\documentclass[a4paper] \setbeamertemplate<> \begin \begin Some text which I would like to write down. \end \begin Let us write this in terms of creation and annihilation operators, using \footnote<$\phi(\vec) = \int d\tilde

\left( e^\cdot\vec>a_> + e^\cdot\vec>a_>^ \right)$> \end \end

enter image description here

I want to write down footnote for some equation, but it is sometimes too long to write down in footnote space. So far I searched similar problem but I can't find proper answer to solve this problem. What I want to know is how do I remove unwanted blank page or how do I increase footnote space. How can I do that?

Is dropping the \left and \right instructions in the footnote material an option?

It's not clear why you're using a footnote, a device that I can't recommend for presentations.
