# A family of MCF solutions for the Heisenberg Group

## TL;DR

This paper studies mean curvature flow soliton solutions on the Heisenberg group, focusing on ruled surfaces, and identifies a family of solutions generated by specific isometries, including the Grim Reaper as a special case.

## Contribution

It introduces a new family of MCF soliton solutions on the Heisenberg group generated by particular isometries, with explicit linear affine motion functions.

## Key findings

- The solutions are generated by isometries fixing the origin.
- The motion functions are always linear affine functions.
- The Grim Reaper solution arises from a ruled surface in 

## Abstract

The aim of this paper is to investigate the mean curvature flow soliton solutions on the Heisenberg group $\mathcal{H}$ when the initial data is a ruled surface by straight lines. We give a family of those solutions which are generated by $\mathfrak{Iso}_{0}(\mathcal{H})$ (the isometries of $\mathcal{H}$ for which the origin is a fix point). We conclude that the function which describe the motion of these surfaces under MCF, is always a linear affine function. As an application we proof that the Grim Reaper solution evolves from a ruled surface in $\mathcal{H}$. We also provide other examples.
