Syncs lectures/calvo.md with its primary source lecture-python-advanced.myst (see #7 for the source mapping).

The lecture-dp copy was last at the initial-setup version (2026-01-14). Upstream commit 8c84d8da (PR QuantEcon/lecture-python-advanced.myst#312, "Update Tom's edits to AMSS and Calvo Lectures", 2026-02-23) reworked it: Tom's edits to the Calvo time-consistency lecture.

After this sync the file is byte-identical to the source. No intersphinx prefixes needed preserving.

Pull request overview

This PR syncs lectures/calvo.md in lecture-dp to match its upstream source in lecture-python-advanced.myst, reflecting Tom’s edits to the Calvo time-consistency lecture.

Changes:

  • Removes the in-document definition/discussion of square-summability ($L^2$) near the money-demand difference equation.
  • Switches the stated regularity condition in the early derivation from “square summable” to “bounded” sequences (notably for $\vec\mu$ and the intended behavior of $\vec\theta$).

We assume that the sequence $\vec \mu = \{\mu_t\}_{t=0}^\infty$ is bounded.

We say that a sequence that belongs to $L^2$ is **square summable**.

When we assume that the sequence $\vec \mu = \{\mu_t\}_{t=0}^\infty$ is square summable and we require that the sequence $\vec \theta = \{\theta_t\}_{t=0}^\infty$ is square summable,
the linear difference equation {eq}`eq_old2` can be solved forward to get:
Consequently the linear difference equation {eq}`eq_old2` can be solved forward to get:
