Abstract
We apply singularity theory to study bifurcation problems with trivial solutions. The approach is based on a new equivalence
relation called t-equivalence which preserves the trivial solutions. We obtain a sufficient condition for recognizing such
bifurcation problems to be t-equivalent and discuss the properties of the bifurcation problems with trivial solutions. Under the
action of t-equivalent group, we classify all bifurcation problems with trivial solutions of codimension three or less.
