RESEARCH
My research is in the broad areas of theoretical computer science and discrete mathematics.
I am particularly interested in algorithms, computational complexity, and homomorphism problems. Most of my work lies at the intersection of the above, namely it is on (the mathematics of) constraint satisfaction problems (CSP) in its many forms.
All my publications are available online.
Here are some examples of problems I have worked on:
 What is the power of linear programming for combinatorial problems [KTŽ15,TŽ17,CRŽ22]?
 Which problems, just like linear equations, cannot be solved by any polynomialsize convex relaxation [TŽ18]?
 Which problems, just like graph cuts, admit a sparsifier [BŽ20,PŽ24]?
 Which generalisations of submodularity admit efficient optimisation [KTŽ15,WŽ16]?
 Which discrete optimisation problems are solvable exactly efficiently [KŽ13,TŽ16]?
 Which counting homomorphism problems can be solved approximately [BŽ20,FGŽ21]?
 Which promise problems can be solved by combining linear programming and linear Diophantine equations [BGWŽ20,CŽ23a]?
 When can maxcut, and beyond, be solved with arbitrarily good approximation [RWŽ23,MWŽ23]?
 Given a 7colourable graph, can one find a 35colouring efficiently [KOWŽ23] and why relaxations cannot solve this problem [CŽ23b,CŽ23c]?
Get in touch if you are interested in doing an undergraduate project, a master dissertation, or a PhD with me. I cannot take on interns (except for, occasionally, Oxford undergraduates) and thus generally do not respond to such requests. I'm happy to supervise highly motivated students with a strong background in theoretical computer science and/or (any branch of) mathematics in any area of in algorithms, discrete mathematics, or computational complexity.

Trivia
My first name is Stanislav but I go by Standa /'stʌn.da/, a commonly used Czech variant/diminutive of Stanislav.
My last name Živný /'ʒiv.ni:/ has two diacritics called the caron
and acute
accent respectively; this can be achieved in LaTeX by \v{Z}ivn\'{y}.
For several special reasons I try to minimise travel but you can always visit me (virtually) in Oxford.
