On a family of negative curves
Javier González-Anaya, José Luis González, Kalle Karu
Let be the blowup of a weighted projective plane at a general point. We study the problem of finite generation of the Cox ring of . Generalizing examples of Srinivasan and K…
Balanced complexes and effective divisors on
José Luis González, Elijah Gunther, Olivia Zhang
Doran, Jensen and Giansiracusa showed a bijection between homogeneous elements in the Cox ring of not divisible by any exceptional divisor section, and weighte…
Examples of non-finitely generated Cox rings
José Luis González, Kalle Karu
We bring examples of toric varieties blown up at a point in the torus that do not have finitely generated Cox rings. These examples are generalizations of previous work where toric…
Universality of K-Theory
José Luis González, Kalle Karu
We prove that graded K-theory is universal among oriented Borel-Moore homology theories with a multiplicative periodic formal group law.
Descent for algebraic cobordism
José Luis González, Kalle Karu
We prove the exactness of a descent sequence relating the algebraic cobordism groups of a scheme and its envelopes. Analogous sequences for Chow groups and K-theory were previously…
