# Lefschetz duality for intersection (co)homology

## TL;DR

This paper establishes Lefschetz duality for intersection (co)homology within the framework of $oundary$-pseudomanifolds, accommodating general perversities and arbitrary coefficient rings.

## Contribution

It extends Lefschetz duality to intersection (co)homology for $oundary$-pseudomanifolds with broad perversity and coefficient ring generality.

## Key findings

- Proves Lefschetz duality in the intersection (co)homology setting.
- Works with general perversities and arbitrary coefficient rings.
- Provides a unified duality framework for $oundary$-pseudomanifolds.

## Abstract

We prove the Lefschetz duality for intersection (co)homology in the framework of $\partial$-pesudomanifolds. We work with general perversities and without restriction on the coefficient ring.
