The components of the LSTM that do this updating are called gates, which regulate the information contained by the cell. Gates can be viewed as combinations of neural network layers and pointwise operations. If you don’t already know how LSTMs work, the maths is straightforward and the fundamental LSTM equations are available in the Pytorch docs.
