Exotic diffeomorphisms of reducible $4$ -manifolds with odd $b_{+}$

David Baraglia

A diffeomorphism of a $4$ -manifold is said to be exotic if it is continuously isotopic to the identity but not smoothly isotopic to the identity. Ruberman constructed the first exa…

Floer homotopy type and eta invariants of Seifert $3$ -manifolds fibering over $RP^{2}$

David Baraglia, Pedram Hekmati

We compute the Floer homology and Seiberg-Witten Floer homotopy type of Seifert rational homology $3$ -spheres which fiber over $RP^{2}$ . We show that they are all $L$ -spaces…

Exotic diffeomorphisms of 4-manifolds with b_+ = 2

David Baraglia, Joshua Tomlin

Let $X$ be a compact, oriented, smooth, simply-connected $4$ -manifold. The mapping class group of $X$ is defined as the group of smooth isotopy classes of diffeomorphisms of $X$ . T…

Exotic embedded surfaces and involutions from Real Seiberg-Witten theory

David Baraglia

Using Real Seiberg--Witten theory, Miyazawa introduced an invariant of certain 4-manifolds with involution and used this invariant to construct infinitely many exotic involutions o…

Irreducible 4-manifolds can admit exotic diffeomorphisms

David Baraglia, Hokuto Konno

We prove that a variety of examples of minimal complex surfaces admit exotic diffeomorphisms, providing the first known instances of exotic diffeomorphisms of irreducible 4-manifol…
