$n$ dimensional space. This paper studies the following the

initial-boundary value problem with localized reaction term:

\begin{align*}

u_{t}(x,t)=\Delta u(x,t)+

\frac{1}{(1-u(x,t))^{p}}+\frac{1}{(1-u(x^{*},t))^{q}},

(x,t)\in B\times(0,T),

\end{align*}

\begin{align*}

u(x,0)=u_{0}(x), \ x\in B,

\end{align*}

\begin{align*}

u(x,t)=0, \ (x,t)\in\partial B\times(0,T),

\end{align*}

where $B=\{x\in \Bbb{R}^n: \|x\|<1 \}$, $\partial B=\{x\in

\Bbb{R}^n: \|x\| =1\}$, $x^{*}\in B$, $0<p,\ q<\infty$, $T>0$,

and $u_{0}\geq 0$. The existence and quenching behavior of the

problem are studied. For the case $x^{*}=0$, the quenching rate

of solution near the quenching time is investigated.Advisor Committee Hon-hung Terence Liu - advisor
