Abstract
We study Legendrian singular links up to contact isotopy. Using
a special property of the singular points, we dene the singular
connected sum of Legendrian singular links. This concept is a generalization
of the connected sum and can be interpreted as a tangle
replacement, which provides a way to classify Legendrian singular
links. Moreover, we investigate several phenomena only occur in
the Legendrian setup. ⓒ by International Press of Boston, Inc. All rights reserved.
