+    r"""
+    Compute the Katz centrality for nodes in a graph.
+
+    Katz centrality computes the influence of a node based on the total number 
+    of walks between nodes, attenuated by a factor of their length. It is 
+    defined as the solution to the linear system:
+
+    .. math::
+
+        x = \alpha A x + \beta
+
+    where:
+        - \( A \) is the adjacency matrix of the graph,
+        - \( \alpha \) is a scalar attenuation factor,
+        - \( \beta \) is the bias vector (typically all ones),
+        - and \( x \) is the resulting centrality vector.
+
+    The algorithm runs an iterative fixed-point method until convergence.
+
+    Parameters
+    ----------
+    G : easygraph.Graph
+        An EasyGraph graph instance. Must be simple (non-multigraph).
+
+    alpha : float, optional (default=0.1)
+        Attenuation factor, must be smaller than the reciprocal of the largest
+        eigenvalue of the adjacency matrix to ensure convergence.
+
+    beta : float or dict, optional (default=1.0)
+        Bias term. Can be a constant scalar applied to all nodes, or a dictionary
+        mapping node IDs to values.
+
+    max_iter : int, optional (default=1000)
+        Maximum number of iterations before the algorithm terminates.
+
+    tol : float, optional (default=1e-6)
+        Convergence tolerance. Iteration stops when the L1 norm of the difference
+        between successive iterations is below this threshold.
+
+    normalized : bool, optional (default=True)
+        If True, the result vector will be normalized to unit norm (L2).
+
+    Returns
+    -------
+    dict
+        A dictionary mapping node IDs to Katz centrality scores.
+
+    Raises
+    ------
+    RuntimeError
+        If the algorithm fails to converge within `max_iter` iterations.
+
+    Examples
+    --------
+    >>> import easygraph as eg
+    >>> from easygraph import katz_centrality
+    >>> G = eg.Graph()
+    >>> G.add_edges_from([(0, 1), (1, 2), (2, 3)])
+    >>> katz_centrality(G, alpha=0.05)
